I got XP Pro SP2 on my laptop I got Windows 2003 Server on the NAS I got Redhat on the file server. Vista is useless and anyway Vienna is due out soon...dunno all I care about in an OS is that fact that ALL of my hardware and ALL of my software will run and so I can do my job. I am businessman, i dont care if something looks pretty like Vista, all i care about is the fact that it does what and when i want. If it looks good , great but its not the most important thing.
I had both XP and Vista on the same computer (duel boot) until my computer bit the dust. I bought a new HP 4-quad, 6 Gig RAM, 720 Gid hd with 64-bit Vista installed. There are some programs that won't run on my computer, such as Flash viewer, so I had to install 32-bit FireFox to view UTube clips.
I have two diff hard drive with two diff boot settings. First one with XP and Vista dual booting and Ubuntu Linux on the second one ...
