You are going to have both WinXP and Win2003. Since your main function in Win2003 would be to code programs, I can only recommand you use it, because it it's faster, and I would also say more stable. I would use Win2003 to code in if I had it! AaronXP: Maybe it was 3 years ago, but it still counts. I couldn't imagine myself coding in Win98/ME... it would take twice the time to make a program, with all the random crashes and all. NT are here to stay!
