haha.. seems like im not really going with the flow here... but i have been using vista ultimate for quite a few months now and i dont have any problems with it...
i guess it depends on your system spec.. but iv seen nothing but better performance and a nicer GUI
i wont go as far as recommending ppl to switch to vista.... but i recommend ppl give vista a shot.. (especially since sp1 is now out)
i am yet to come across any driver/incompatibility problems that have hindered my usage of my computer.
