How Small a PC Is Too Small?

Banner~! recommends an article in IBTimes on the search for the ideal size for an ultraportable computer. One device mentioned is Paul Allen's FlipStart, discussed here recently. After watching early users fumble and nearly drop an early version of the FlipStart while trying to perform a three-finger salute, designers ended up including a single key labeled "CtrlAltDel" in the version that will be shipping soon. From the article: "Each device maker... has a different sense of how small an ultra-mobile can get before it becomes impossible to use. For instance, Microsoft thinks the tiniest screen possible measures 7 inches diagonally, but FlipStart Labs settled on 5.6 inches."

      CTL-ALT-DELETE is a Windows issue, but it is symptomatic of a bigger issue: interfaces need to change with the form factor.

      When I started writing PDA interfaces, I simply shrunk down what I'd been doing on desktops, with a few tweaks. Most PDA apps appear to be designed this way.

      After a few years, I realized that while you could create a workable interface this way, it wasn't natural. On a desktop, text entry is easy (you have a keyboard) and navigation is hard (you have to take your hands off the keyboard), so you use your copious screen space to put a lot of data up at one time. On a pure PDA navigation is the easiest operation because you have your stylus in hand. The popularity of PDAs with keyboard (e.g., smart phones) is in part due to unimaginative user interfaces; even so it is easier to navigate with the stylus than enter text via any method other than a full sized keyboard.

      My recent UI designs tend to eschew things like forms and combo boxes, instead giving over the entire screen to enter one piece of information, perhaps with a generously sized scrolling list of choices, or a big fat calculator interface for entering number values. Backward forward and upward navigation is available through consistently placed on screen buttons. Navigating to a data data entry "form" automatically puts the focus in the right place, since there is only one right place for it to go. This means the number of taps to enter a sequence of data items is the same as if you had a multi-element form. There are other tricks you need to make this work, but the result is that with careful design data entry in the most common cases can be made much faster than on a shrunk down desktop interface, with the uncommon cases being about the same.

      It is likely that every style and size of mobile device has unique characteristics that change the optimal interface on that device. I can see this even on laptops; some programs really are pain to use on laptops because they are designed around the assumption that most people have 19" screens or larger. One program I sometimes have to use at work uses a proliferation of nested split panes. On a 25" screen, you'd set up all the information you need in a bunch of boxes and keep it that way. Any time you need a piece of information, it'd be like picking out Florida on a map of the US; you look where it was last time. On a 15" screen the same interface doesn't work at all. There isn't enough room, so you collapse nearly everything into a (recursive) nest of vertical and horizontal lines, then pick through them when you need hidden information.

      Its a feature because it enables better security.

      But does SAK really improve security? I would argue that in practice it is useless. As you pointed out yourself, physical access to the box permits full access to the CPU (though the data on the hard drive might remain encrypted) and if anyone can subvert the machine over the network then they could replace the login program itself with their own version that popped up when the SAK was hit.

      Seems to me that SAK only buys you security if you assume that your OS is not already compromised AND a malicious user with physical access to the box who does not already have Administrator access is running a full-screen application that looks like a login prompt in order to snatch passwords AND they did not already install a hardware keylogger. Times have changed since ~1990, and this use case is very limited to me. The malicious user can just as easily find a local privilege exploit and snarf the entire password database and crack it at their leisure or just run an application that looks and behaves like Explorer.exe but records keystrokes.

      Christ, with the standard linux install, I can log in as root without knowing the password if I have console access, just reboot and trigger single user mode during startup. How is that secure?

      It's exactly as secure as any PC with a BIOS that allows booting from removable media. I can circumvent Windows security by booting a custom Linux, resetting the Administrator password, and then booting into Windows.

      I COULD secure a Linux system by:

      1) Enabling a BIOS password.

      2) Allowing only booting off the hard drive.

      3) Using LILO and forcing it to boot the kernel with no prompting for kernel parameters, hence no single-user mode before password.

      This still leaves the ability to open the case and reset the BIOS or replace the hard drive.

    It is obvious that keyboards/pads have a minimum size. Fingers limit that. Also, if the keys are too close together, typing is slowed because more than one key is frequently depressed.

    The screen is also limited in its smallness by what is comfortable. I use my phone to read books, but I have heard many people claim (who havent tried it, of course) that the screens on phones are too small to read on. In my experience, screen size is not important as the size of the individual letters (or characters) in the text is what is important. Since my current phone allows me to blow the text up to a size that is larger than the typeface on most children's books, I cannot see the problem.

    The limitations on the device size probably depend on what it is used for. If it is a phone, it needs to be large enough to be comfortably held for a long phone conversation. Phones that are too small are irritating and easily misplaced. If the device is a PDA, the screen is probably the limiting factor. It should be about the size of a screen and not much thicker. Ideally, this screen should be a size that would fit in your pocket, something that "Pocket"PC's generally do wrong.

    If the device were something like a portable computer, with perhaps a bluetooth or WiFi keyboard and screen, there is probably no limit on its smallness. Why not make a USBkey style computer and keep it on your keyring? At 4+GB, such devices can already contain a decent suite of software. Removing hardware links to the device itself would free it from size restrictions. Theoretically, such a device could also be booted from any computer as its hard drive (Knoppix style), so you could take your computer anywhere.

    There is no realistic way that a PC can be too small. As long as it so small it is easily lost it is just fine - I would *love* one that could hang on my key chain.

    What *can* be too small is the interface. I do not like a tiny screen nor do I like a tiny keyboard (or other input device). I have quite large hands, even the smaller "full size" keyboards are uncomfortable and only useful as a portable device, not my main one.

I do not think the descriptions said and I have never used one and that seems about the only feasible way) sense where you fingers hit. Other than some RSI problems with my finger hitting a hard surface (and that is fixable for a permanent station) that can be made to be any size or layout.

    I also prefer small text, but I prefer that on a larger screen. I am currently using a 15" LCD and that is about as small as I comfortably go. I do not like writing much code in it either, my 21" monitor went kaput and this is all I could currently get. A 17" screen is the smallest "normal" lcd I like and I prefer a 19". I know of no current technology to fix this one, but there is no reason it can not be fixed.

    Of course, that is for what I would call everyday use. If your computing power is in a small package there is no reason you can not have a docking station for full size stuff and quite small for carry around. I *can* hit some very small keys with a stylus and use a very small screen (lets face it, many of us currently do - or did - with the palm tops). That is nice for something I pull out of my pocket and use for a few minutes. Add in a few larger keys to mash and I can even game, navigate for MP3's, use a cell phone, add something to a calendar, or other typical small device things with large easy to use buttons. At that point I would consider the size my finger can reliably hit and the number of buttons to be the limit (small could use a stylus, but I do not like that idea for simple frequently used functions).

Bradley originally designed Control-Alt-Escape to trigger a soft reboot, but he found it was too easy to bump the left side of the keyboard and reboot the computer accidentally. He switched the key combination to Control-Alt-Delete, a combination impossible to press with just one hand (this is not true of later keyboards, such as the 102-key PC/AT keyboard or the Maltron keyboard)."

    Isn't it ironic that the designers are celebrating the fact that they have reintroduced the possibility of an error that the designers of old foresaw and attempted to avoid by a three button combination that could not accidentally be triggered with the slip of one hand? Or perhaps it is the fact that Windows these days has more than one function linked to that key combination, forcing the dialog anyway...after which you are forced to "cancel or allow" the action that you selected from the dialog box that was triggered by the keyboard combination.
