    While using unstable Windows 95 at home, I admired apple for creating stable operating systems such as Macintosh OS, which I used in my university. Yes I believe Apple has always been better at making OSs than microsoft

      Odd, I always had Windows 95 crashing even when only one app was running, and have little problems running multiple apps on classic MacOS as long as I don't run anything from Microsoft or Netscape.

      The point about Win95 (and 98 isn't much better)is: is it the app crashing that corrupts the Protected Memory, or is it the OS killing itself.

      I'm sorry but I have to cry bullshit on this post. I work for the the IT department for a reasearch university in New Mexico (yea, laugh now but our U pulls in loads of reasearch money and we have one of the top Engineering schools in the country and we're in the top 50 in Computer Science) and we have widespread use of OS X, mainly in OS X Server but you would be surprised at the ammount our of sys admins running Macs with OS X (our entire NOC is running OS X as admin computers). It's a great combination of useablility (i.e. MS Office and UNIX Sys Admin tools nmap, ethereal, etc.) that just doesn't happen in the Windows environment. And yes, I realize you aren't talking about system administration, you are talking about end users.

      I'm not sure what types of software that you were running but they must have been extremely poorly written. I mean OS X crashing more than ME?!? Come on, give me a break, I don't recall ever seeing a BSOD on a OS X (maybe the swirl that never ends) but if you know anything about *NIX in general, you can kill -KILL (PID) any process that is causing problems. Your comparison of Max OS X in general to ME is almost absurd as ME is based on partly on technology from the old DOS days, where OS X has compatability with classic, but the underpinnings are not the same. A much better comparison would be NT/2000/XP to OS X, but even there the reliability is not the same.

      I personally have a Mac running panther, along with 2 PCs, one (sadly requied) running Windows XP and one running Linux. My current uptime (not max, which is 66 days) on my Mac is 34 days (the MAX uptime i've ever had on my XP machine is 22 days), and security reboots aside I've never had a crash, lockup or any other problem with OS X. I can't say the same for any Windows operating system I've ever run, although with XP my reboots are occuring with less frequency. And NO I'm not a Mac fanboy, I really prefer working on my Linux system, Mac comes in at a close second. And working in IT for 12 years, Mac's are, if not the easiest to deal with, they are close. No wonder you post as AC, but the fact that you're post was modded up shows that those with mod points are on crack.

      As crappy as Win95 is, OS7 and 8 were a lot worse in terms of stability. I've never met a OS7 user who hasn't had to "rebuild his desktop" at least every other week.

      Well, let me introduce myself. I ran System 7 or 8 on my PowerMac 7100 for over 6 years and never rebuilt the desktop or had unexplained crashes. I kept my system folder very clean and avoided any exotic extensions (i.e. Now Utilities) that hacked the OS.

      I think the operative word in his recollection is the word "was"... Indicating that we're talking Mac OS 7 or Mac OS 8, not OS X.

      Regardless, a well administered mid-90's Mac was still arguably more stable than the average Windows 95 machine, 'pseudo protected memory' be damned...

      There's a fileserver/database host pizzabox mac I set up in 1998 for a network-noob arts collective that ran sans reboot for two years, daily (even weekend) moderate use, until a power failure forced the issue. Some dude just changed the jaz disks every couple of days. I used to check up on them but it just worked, and finally I checked back a couple of years ago and it still chugged along, only a few reboots over the 4 years.

      System 8.1, filemaker 4 solution with 45 related files and 600K+ records, and 20K+ word and excel and email files, a cheap old headless mac. Set that config up a few times over the years, for small organizations, a lifeline to them, hassle free and useful.

      When I tried the same thing three years ago with an old win98 box (not enough cpu muscle for Win2k, and no budget, nada, zero), well, let's just say that after getting a few frantic phone calls ['it just shut down' - 'why do the fonts suddenly look all funny'] I went out and got another crusty old mac to do the job, problem solved. Not bad for a non-server OS, when scaled down properly.

      I think the simple idea behind the desktop file is actually pretty powerful, and mostly overlooked by contemporary implementations. The idea is that you have metadata (icons, etc.) contained in the file itself, which allows the metadata to be moved together with the file, but at the same time having efficiency while scanning because the same data is copied transparently in a central database (which can be rebuilt at will).

      On systems in which a similar approach is not used, either the metadata is not part of the file, or the individual files may have to be scanned for icons and other info quite often (*ahem-windows*), which may take a substantial time.

      A file systems in which metadata is handled as part of the file *but* transparently stored in a special way should ease the problem. I guess that's what the people at M$ are trying to do with Longhorn, among zillion other things.

    Apple started with a decent OS for the Mac, given the hardware at the time. No innovation to the kernel happened afterward throughout the nineties, resulting in the worst modern OS on the planet by MacOS 9. Steve Jobs comes back, identifies how aweful the OS is, and rightly abandons the horrible piece of software. Apple creates MacOS X to replace it out of Mach, and BSD, resulting in a decent OS.

  4. Re:Pity about the os9 GUI by Anonymous Coward · · Score: 5, Insightful

    Alot of people don't understand the principle reasons for the GUI change. One was to make certain that people would see the distinction between the OS X and Classic modes. It was very important for Apple to get programmers to write native software that they make it very clear that the program they are using is not OS X native. Also, there was the necessity that older users be made constantly aware that this was a new OS and that it had very different capabilities. Apple wanted people to learn to use it differently. These are all really more important than the attractiveness of the UI. I really think they blew it on the way textures changed and a few other things. But, for the most part it is very good.

    Hey, I loved OS 9 too, and even the older Mac OS' got my heart beating fast.

    But I mean, OS X just has to be the next step. There's only so much Apple could have improved OS 9. I do VERY much agree with some here about the way OS 9 looked, I like it as much as/more than I like the look of OS X. If Windows XP is the "Playschool" interface, then OS X is the "Mattel" interface.

    I really, really wish Apple would provide ways to completely skin the OS from System Preferences, such as making it look like OS 9 while keeping the features set. That would be nice. Even though some programs now can do that, I'd love Apple to do it.

    In the future I can only see good things for Apple. And who knows, maybe they will get closer and closer to integrating Linux, though BSD isn't a bad option as it stands.

  7. Re:Pity about the os9 GUI by Bishop · · Score: 4, Insightful

    This highlights one of the problems I have with KDE GNOME. Both projects had the misguided idea that a gui that looked like Windows would be easier for users switching from Windows. Ofcourse the opposite is true. If a gui looks like Windows users are going to expect it to act exactly like Windows. When the behaviour is a little different users get frustrated and confused. It would be far better to have a completely different UI that is userfriendly.

    That said, I am not sure that Apple switched the UI for reasons of useability. There are so many UI mistakes in OSX compared to MacOS9 that I not sure if Apple was ever thinking about good UI when designing OSX. ;-)

  10. Mistakes in OS X v OS 9? by wfolta · · Score: 5, Insightful

    Most of the "mistakes" I've read about boil down to simply operating differently.

    Remember, the OS 9 GUI was originally designed for a uni-tasking computer with a tiny screen. It was brilliant. But over the years, more and more features were welded on, Frankenstein-style and it ended up being inconsistent and unwieldy. Curmudgeons now bitterly complain that it was better, but it sucked in so many ways...

    For example, the Apple menu which became the dumping grounds for anything that didn't fit elsewhere. It was originally meant to be a place where mini-applets resided to provide you with a tiny bit of multitasking. (The calculator, Chooser, etc.) And let's not even mention that the Apple menu could change on a per-program basis even though it was supposed to be independent of the currently-running program.

    How about the File menu which is featured in every program and mostly contains functions that don't have anything to do with files, or even the program in which it is featured. Then we have the much-vaunted Finder which does things absolutely inconsistent with all other apps. (I.e. CMD-N creates a new folder, not a new window/document.)

    How about another OS 9 Finder gem: go to one window and select some files, go to another ans select some more files. Guess, what, the files in the first window are no longer selected. Would you put up with this in any other app? NO. You'd complain about Apple's GUI guidelines, and rightly so.

    But OS 9's GUI has achieved sacred status in the minds of the inflexible and so you can't argue with them.\

    (The most prominent curmudgeon is the Applelinks guy, who has become a parody of himself with all of his protestations about being a MacOS X guru yet wanting his old kludgy and inconsistent OS 9 back. Sort of like the sports "expert" who complains about the end zone in baseball. He bitterly complained about performance for a long time, but it turns out he had all kinds of "haxies" to make OS X look like OS 9, then he ran in a tiny partition without enough RAM.)

    It may be Jobs's fault, but in any case, the issue is moot. The choice is not between Aqua and the Classic look-and-feel. The choice is between Jobs and OS X or a dead-in-the-water Apple still making incremental upgrades to OS 9 and getting less relevant by the second. Regardless of Jobs's faults, he did save the company, and I prefer a modern OS with a good GUI to an ancient OS made by a dead company with a great GUI.

    Although, for me, I prefer OS X in every way except for the Finder, including appearance and interface. It might help that I studiously avoid Carbon apps (except for the Finder). And of course I like UNIX, which helps. But on the rare occasion that I boot back into OS 9, I feel very constrained and limited.
