MacOS
1. Those damn bombs.
2. Hides damn files on you,(one of the good things about windows is that you can see everything)
3. Can't switch between multiple IE windows easily(with windows i can have 20 open and switch with ease)
4. One godamn button?
5. Video cards suck for the Mac, yes even the new radeon's and geforce's, A G4 is supposed to be a super computer not a computer with low level video cards.
6. No more SCSI on the newer Macs
7. A beta that costs money(and yes i did buy it)
8. Appletalk is the slowest thing i have ever seen, I'm forced to use a 3rd party software because Apple likes to be proprietary.
Windows:
1. Everything it does is in RGB (not good at printing companies)
2. Have to tweak it so it runs fast(why not make the fastest settings the defaults?)
3. Desktop clutter.
4. The near future of Microsoft's .Net strategy *cough* monopoly *cough* controlling *cough*
5. Long as install times for the OS itself.
6. Having to know every nook and cranny just to disable stuff from starting up(Macintosh extensions manager anyone?)
7. DLL files, even whistlers attempt at controlling them is suck.
8. that damn registry
9. too many wizards. How about simpler ways to change things instead of being asked 20Q
BeOS:
1. Lack of drivers, but getting there
2. Lack of software, don't know if it'll get there
3. It's young(but damned stable)
Linux:
1. startx?
2. KDE, Gnome, windowmaker, (can we decide on a single gui here)
3. Good for servers bad for people who can't even plug in their mouse and keyboards without everything being color coded.
BeOS is mondo cool, too bad you cant do anyhting with it. Linux is OK, can do alot, if you know alot and dedicate your life to it. Windows, what else are you gonna use? And it is getting somewhat better. MacOS, the best gui out there. Macs are very very friendly, you can even configure them as a server with ease. Macs can do as much as a Windows machine. But they're damn expensive, and some components are sub par for what you could get with a pc, and all of the software is expensive too. MacOSX? beta's pretty good, not as user friendly, looks alot better since macexpo. but is it enough?
I say we all start our own OS AnandOS. The gui of MacOS9, the core of BeOS, throw in some stability of linux, make a monopoly, and have fun.
