Windows Vista = Microsoft's doom ?

ok , i know i didnt post for a umh ... long time . My new post is maybe a bit technical this time . Microsoft released the new version of windows , windows vista , on the 30 th of february . I tested it ( beta ) and seriously , i prefer my windows xp . I still remember reading a review (from www.download.com) , its says vista is more like a sp3 ( service pack 3 ) of xp .
Vista added some new things in and , ok looks better . However , theres basically no use of vista when you do not have good hardware , why cause it switches the new features off when your computer cannot handle them . Something else , a read about mac user switching to vista and did a switch again , back to mac . Basically , this version of windows is not a mac or linux killer . However , windows still retains its only advantage , everything works on windows . For example , in linux you will need to spend lots of time and effort to get your modem working and connect yourself to the internet as most modems are win-modems . I am still trying to make my every software to work on my version of linux and switch to linux eventually . Hopefully , I can release a version of OS that will remove the advantage to microsoft and prove itself as a windows killer .
