well im running on win2k pro. its alot more stabil than 98/95 when running progs because if a prog locks up in 98/95 your screwed in 2k you can use the task manager...that manager is ALOT more efficient in 2k. winme is trash, i cant tell you how many times i have heard, "well i had win98 and tried upgrading to winme and lost everything" its had the most reported bugs out of all windows. winxp needs alot of system resources. it eats up ram like i eat krispy kremes. if i actually had any balls i would go with linux. i dont like windows but its the most familiar thing im with. i just am told linux is hella faster and alot more stable...the only problem is though, is i hear you NEED to customize it to get full potential. im not planning on learning O/S code anytime soon so im thinking i might scratch that idea. ^_^()
