Incidentally, so are a lot of companies. They're sticking with XP until 7 is released; something like 4% of companies who use Windows as their operating system have made the transition to Vista. Not sure how accurate that number is as I've seen it quoted as high as 15%
I think it suffers mainly because of two reasons: it's a resource hog, almost unnecessarily so due largely in thanks to things like Aero and the sidebar, which when disabled speeds up the computer tenfold. Secondly, I think it was released too early mainly for the reasons listed above. The minimum specs required for it memory-wise is 512meg, but the bare minimum should be 1gig, as on 512 it takes FOREVER to open things, and you can't really run more than one program at once.
I bought a laptop so I could do my distance course while working at ski resort. I didn't need anything flash, nor afford something flash, so I went for a budget Compaq Presario, a couple of months after Vista was released.
I walked into Office Works hoping to find a budget laptop with XP on it, but no dice. After looking around other places I realised that everything was being sold with Vista pre-installed so I went ahead and bought it.
And my God did it suck major ass. For a straight out of the box laptop (1.78ghz, 512 ram, 80gig HD) it ran slow from the get go. Then I couldn't get it to network properly with my parents PC which had all my files that I needed. So I was initially unimpressed.
The networking problem, however, wasn't a Vista problem; it was an obscure setting in Norton Internet Security that did it, something that I only found out months later browsing for a solution online.
I could barely run more than one program at once without lock ups. When we moved over to NZ, it just collected dust because the desktop was obviously faster and easier to use. I was considering doing the 'upgrade to XP' and looking online on how to do it, and saw it'd require a complete wipe of the HD which I wasn't keen on. So I cracked open the RAM slot/area/thing to see if I had any slots free, and it turns out I had one. So $40 on 1 gig of RAM later the thing was running superbly (total 1.5 gigs).
Everything loaded normally (usually faster than the desktop pc with XP) and it began to be a real dream to use. It's much, much, much easier to install new hardware and it's also pretty 'smart' in that it can do things automatically that you used to have to do manually and fiddle with, that goes slightly beyond the knowledge of your average PC user.
I don't miss XP at all now, and there's nothing on it now that causes me any problems or annoyances. Though the things that did I simply disabled. I think EVERYONE would find Vista the suck straight out of the box. You have to tweak it to your personal needs and tastes, which is when it starts to outshine XP.
Haha, just realised this post is like one big advertisement. I'll go and see if I can wrangle some of Bill's money.
