Well, I am sort of on both sides of this "war" - 2k vs XP. 2k I can admit had fewer compatibility issues since my Audigy actually worked right (!!!!) and also it wasn't so newbie friendly, and all this new GUI stuff XP has just takes up resources and is too newbie friendly that its scary.
Anyway, XP does have ClearType and I use an LCD panel as well. Also, when a program crashed in 2k, sometimes i had to reboot before i could run it again. In XP, if it crashed, I just closed it and restarted it and no reboot was required.
XP does reboot quicker, but it has Networking problems - I have problems trying to share a printer that is connect to a computer using XP. I have a router and XP seems to not like it too much.
To sum it all up - Windows is too buggy. If Linux was the more popular, newbie friendly OS that every software company made software for first, I would switch to Linux. Games have to be WINEd to run on Linux which is a pain, etc etc.
Getting back on track, I really don't know what is better - 2k or XP. I definitely would tell all 9x/NT/ME users to use 2k or XP, but which of the two is greater, I think it might be XP. This is what I have noticed:
XP seems to go slower than 2k, even slower if you have the new fancy GUI set up onto it. However, it is much more stable.
2k seems to be more compatible with things, but then again, if it isnt compatible with something it has a good chance of crashing the program.
I haven't had any Windows crashes on XP yet, but I have had a few on 2k and they all resulted in STOP errors (sort of like the NT version of the blue screen of death, and yes, STOP errors are blue screens of deaths for those of you who havent experienced them)
Well, if you want speed and compatibility go 2000. If you want ClearType (yay!) and stability, go XP.
P.S. I have been running XP since January 7th, right after I built my computer and then installed XP, and it hasn't been turned off yet. It's not that safe since I have to reboot for the security updates to install, but I am going to wait til my old man's birthday before shutting it down. 😛
