Currently I am testing Windows 7 7000 x86 on one of my laptops (fairly new . Lenovo 3000 n100) and am very Impressed with it so far. But It is still in beta mode and I have found quite a few bugs that need work on, or Modifications from MS to smooth it out.
As far as Vista, forget it. I have run it
and tested
it and repaired it
for a few people (and companies) that I do Computer Consulting and Network setup's for.
I Own a copy of Windows Vista x64 and x86 Ultimate and have no
reason yet to install it on any of my computers.
I have 8 computers that I use constantly
and right now I have Windows XPP x64 on my big box (Gigabyte GA-965P-DS3, Intel Core 2 Quad Q6600, 8192 MB, NVIDIA GeForce 8600 GTS & NVIDIA GeForce FX 5200, 3TB's of HDD's). And Windows XPP x86 on 4 others (2 laptops 2 desktops) Windows XP home on my wife's (minitoy) AcerOne and Windows CE 5 on my iPAQ 5555.
I have had computers since 1977 (the first I'll bet you never heard of TRASH80 {Radio Shack TRS-80}), and have used MS OS's since 1987-89 and still have the original copies of Win1.1 - now Win7, I also have servers OS NT3.5-2003.
I Got impressed with Windows when I met Bill and Paul, (the 2 who started Microsoft), back in 1985 and have been a fan since then.
I like Linux but it is not that compatible with the work I like to do, and no matter what Linux fans claim, you still have to work out buggs
constantly. The only MS O.S. that was like the buggy Linux was Windows ME. I believe that was a glitch forced by the marketing group at MS.
