actually this dual boot (OS) thing is not a really big deal, nothing much diff than u use single OS, it just give some satisfaction to certain group of peoples to enjoy all features in that multiple OS, i'm also an ex- dual boot user, previously doing it because that time certain games still not optimize (in terms of patch) in vista and stable in xp, but at the same time i was eager to use new features in vista (like aero theme, dreamscene) and i felt quite easy to use vista for watching movie & anime, so installed both OS... but now since most of games can be played in vista without no problem (and also due to not enuf space in my hdd, and dun have money to buy a bigger 1), decided to have Vista only, quite satisfy with it...

for those said vista can kill ur sytem, pls give me ur evidence, dun just say it bluntly...

hihi, XP became 'anak tiri'
also happen to me last, sometime up to few months didnt boot xp
