yay simple is the best! but i've heard bad stuff about vista, and how it wont do some stuff, ect. so if i go buy a windos OS then i have to call and give my serial number? (i have one on my old comp >.o)
If you buy a Windows OS no you wont. If you use your current disc yes you will.
Plus VIsta is not as bad as everyone here makes it out to be. I haev run it flawlessly for a year now. I have run over 95% of the apps i have wanted to. Over 90% of my games run now. Only some really old games that are Windows 95 based have a really hard time working. So Vista is not that bad...
