    Yeah, but then you're stuck with the dinky little screen half the time, and the hand-cramp-inducing, RSI-aggravating, profanity-provoking reduced-size keyboard all of the time, which is just plain wrong.

    With a 19-inch "laptop", you've basically got an ultra-portable mini-desktop that you can use *anywhere* (well, anywhere with a chair and a table or desk), that takes three seconds to set up and three seconds to take down and can also double as your main workstation so you don't have to worry about syncing. Going to visit your parents for the weekend? You just fold the thing and stick it in the car: no cables to unwind, no separate pieces to lug (except maybe a mouse, which weighs nothing and fits in a pocket), just grab it and go. You can use it at work, at home, at the relatives' place, at the hotel, ... anywhere. Well, not *anywhere* in the standing-in-line-for-the-waterslides sense, but anywhere with a table and chair, i.e., pretty much anywhere it's practical to use a computer anyway. (Okay, airplanes... but what percentage of the laptop-buying population *really* flies more often than three times a year or so?)

    This is not intended to displace the sub-14" laptop for people who really want to be able to use the thing balanced on one knee while horseback riding and are willing to maintain a separate desktop for indoor use. That's what nine-inch subnotebooks are for, or handhelds. The super-sized laptop on the other hand is aimed to displace desktops for people who would like to be able to move the thing much more easily.

    > I thought the idea of a "laptop" or "notebook PC" was so that it was portable.

    There's portable, and then there's portable, and then there's portable. My prediction is that it's the average-sized laptops (14.something-inch display) that will eventually fall by the wayside, because they're a poor compromise. They're not portable enough to use while standing in line, for instance. You can't balance the thing on one knee, either. And the keyboard isn't suitable for prolonged typing sessions. And you have very little screen real-estate. It is good for some things, but a subnotebook in the 9-inch range is almost as good for most of those purposes.

    If you're going to need to sit down and set the thing up on a table to use it anyway, you might as well use a 17"+ model, especially if the weight-to-diagonal ratio keeps dropping. Among other things, this gives you a full-size keyboard, so that you can touch-type and not need reconstructive surgery on your hands as a result. But it's *way* more conveniently portable than most desktops. For trips, you can easily pick the thing up, toss it in the car, and use it in the hotel when you get there. College students can take it home for the weekend. There's no rat's nest of cables to plug and unplug (with the accompanying end-user concern about getting things hooked back up correctly). Also, it's not so heavy that a small woman would be afraid she'd drop it (a common concern with moving desktop systems).

    There are still going to be some niches that the 14-15" laptop would still fill. It would fit on an airplane tray table, for instance, so people who fly a lot might want one for that. But for most people I would expect either a larger or a smaller option to be preferable, depending on their needs. Indeed, some people mind decide they want both, a 19"+ portable desktop replacement that they can carry into hotels and things and use at any table or desk, and an 8"-or-so subnotebook that they can carry in a large pocket and hold on an open palm in a pinch while hunt-and-peck typing with the other hand (or use a stylus or whatever). Plus maybe also a tiny model that also has a cellphone feature or can be worn as a wristwatch, for very simple on-the-fly tasks that don't require a lot of I/O. (Remember the calculator wristwatches that were popular in the 1980s?

    Ah, but feather is lighter-weight than bzip2 and more aerodynamic and streamlined, so it uses fewer system resources (especially RAM). Also, due to the way the strands interlock, it gets a slightly higher compression rate. Finally, it's designed so that if parts of the file get corrupted, the other parts can still be unfeathered and recovered; only the corrupted parts are lost. This is especially useful in the case of tarballs, which may contain numerous files, most of which may be recoverable in the event the whole thing gets truncated or corrupted.

    Also, feather comes with a kernel module that works with tar and GPG to create a compressed and encrypted loopback filesystem; this module also does software RAID levels 5 and/or 10, splitting the files redundantly across multiple feathered tarballs which can be on multiple physical disks or even mounted over the network.

    > Log on to Linux as root, which is in effect what most people do with

    This is where safe computing practices come in. I run as root all the time, but I don't run software I don't trust as root; if I'm running something dangerous, I throw it in an account with no privileges and, importantly, no read or write access to the data in my home directory.

    Safe computing practices work on Windows too, incidentally. I used Windows 95 OSR2 for years and never had any problem -- but, of course, I didn't use vulnerable client software (e.g., Outlook), and Win95 doesn't have a lot of ports open by default; I used NetBEUI for SMB/CIFS, so it wasn't routed over the modem, got my mail with Pegasus Mail (later Gnus), used a safe web browser, didn't execute executable attachments, downloaded software only directly from the authors themselves (no warez or cetera), and so on and so forth. In general, I used my head for something other than holding down my neck.

    This is, of course, substantially harder when you're going to let end users touch the computer, but even then, a certain degree of safety is possible. The computer my parents use, with Win98SE, has been running for going on five years now, and the worst thing it ever got was Gator -- and that only happened once. Of course, Outlook Express is not present on the system, and there's no desktop or start menu shortcut for IE, and a registry merge in autoexec.bat cleans certain unwanted things out of the Run keys, and I look the thing over from time to time. Oh, and it's behind IP Masquerade, so worms are a non-issue, and does not have a floppy drive, so no boot viruses either. For a home-user system, this is adequate.

    Indeed. Any time an end user asks me about security-related issues, the first thing I always ask is, "What program do you use to get your email?" (They don't know, of course, but I'm not asking to get an answer.) Then I discuss the fact that most mail clients don't automatically _do_ anything when they receive an attachment, except for display it on the screen (e.g., if it's a picture); they don't follow any instructions the attachment contains, so the virus doesn't get activated. Then I tell them that the exception to this is Outlook or Outlook Express, which automatically launches certain kinds of potentially dangerous attachments. Most of them shrug and say "Huh", presumably figuring that if they get infected they'll take the thing in for service, but occasionally someone is concerned enough about the issue to ask me how to find out what mailreader they're using (so I tell them about Help->About) and what ones are safe (I always mention Pegasus Mail, which is easier to use than OE and, if you don't count the collaborative calendaring stuff that home users have no use for, more featureful than Outlook; its source is closed, but end users wouldn't know what to do with source code anyway (if you show them a command prompt and type dir /s they think you're hacking); it does cost nothing, which *is* a selling point for end users; it has the downside of only being available for Windows, but people who were formerly using MSOE don't care about that).

    Of course, about a third of all end users get their email in a web browser, which is not *entirely* safe if it's IE, but is still much safer than Outlook. I've been fighting Outlook mindshare since I first heard the announcement that it would support Javascript in email, back in the mid nineties. I was flabbergasted that such a feature would even be considered, much less announced and implemented. What were they *thinking*? I mean, there are exactly *zero* possible legitimate useful purposes for such a feature, and any first-year computer science student can tell you the security implications are, basically, that you're totally hosed.

    I'm not really anti-Microsoft. I don't use all their products, and prefer an OS that's a little more configurable than theirs, but they make some cool stuff, and their OS is, on the whole, really not a bad choice for most users. But of all their products, Outlook is the one that makes my blood boil. There is absolutely no question that the world would be a better place if Outlook had never been developed. It is a plague and a nuissance, the foremost bane of the administrator's existence, and the difficulty of uninstalling (the Express version of) it is hands-down the worst thing about Windows XP.

    You know, that's a good idea. They're making the updates anyway, right? They could hire an intern for virtually nothing to slap together the autorun code to start the thing installing, and then they could charge the retailers about twice what it costs to mass-produce the things (i.e., peanuts), and let the retailers mark 'em up another 100%, and they'd still cost pocket change. They could print the year and month on the thing (it would, of course, only work with the latest desktop OS release -- but would contain all the free patches; so, for the current one you'd need any version of Windows XP) and issue a new one every month. It would be dated forward when produced so that after shipping the stores could put it on the shelves (or in the checkout line) a couple of days before the month printed on 'em; the turnaround time would still be a marked improvement over the current average. You pick the thing up along with your groceries, stick it in the CD-ROM drive, and no further user action is necessary; it runs in the background, determines which updates you don't already have installed, installs them, and then gives you a dialog that says the update will take effect the next time you restart your computer.

Households who spend more time on the internet have fewer users per computer, on average; it is not unusual in the lower income brackets for families to maintain one computer with internet between three geographically-close houses; some kids have internet at mom's house, but not at dad's house, or only at grandma's, or cetera, and even many adults go to another person's house to use the internet; these computers generally are only turned on for a few minutes a day, even though they may have 10+ different users per seat. They also spend up to 25% of the time in a non-working state, sometimes for several weeks at a time, usually due to configuration issues, but also malware, hardware failures, the phone being disconnected for weeks at a time due to billing issues, and other factors.

    Windows Update is *not* a viable option for these sorts of setups.

    Another significant percentage of users turn off Windows Update to avoid being bugged, because it's easier to get rid of the dialog boxes by turning it off than to make it fully automatic when turned on. And a further significant percentage of those remaining just keep hitting the Later button.

    I don't know what the solution to this problem is, but Windows Update as it stands now is not a complete solution. Making it easy (or the default even, but definitely not the *only* option) to have Windows Update not just download in the background but also *install* silently in the background fully automatically without ever prompting the user at all would help some, but it still doesn't deal well with the bandwidth issue.

The onboard video may have super-hip 3D acceleration, which I suppose is great if your primary PC activity involves wandering around mazes collecting weapons powerups and shooting things with them, but the display glitches you get with most onboard video "cards" make them unusable for anything *other* than games, as far as I'm concerned. The first time the mouse pointer causes whatever's under it to shift leftward one pixel, or changing resolutions results in odd artifacts, or whatever, I ditch the new video and go back to the 1998 technology that *works*, darnit.

    Onboard sound is typically similarly hideous, usually lacking features that have been standard on soundcards during the 486 era, such as hardware general MIDI playback and a decent wavetable. (Though I suppose the quality of the sound card output doesn't matter one way or the other if you use the speakers they ship with most PCs.)

Otherwise, those "blind" spots have almost no impact on your vision. As your gaze passes over something, it theoretically blinks out for an instant (if it's the right combination of small enough and far enough away), in that your retina is not perceiving it for that instant, but as your cerebral cortex processes and intereprets the informatin it is receiving, it smoothes that over automatically and fills in the blanks for you.
