I've been running Vista Business on my Vaio SZ440 laptop. I'm very happy with it, particularly since the release of SP1. I don't find crashes or lock-ups any more frequent under Vista than I did under XP. I do lilke the Aero glass interface and, yes, it's only a cosmetic change, but it's a nice one. I also find I like the Sidebar very much.

I can run everything that I need to under Vista, including a number of arcane programs that were written for XP. When I first got this machine, I seriously considered downgrading to XP, but as time went on and the bugs got ironed out, I found less and less reason to do so. I have a number of other machines that run XP and I find that, when I use them, I miss some of Vista's features. In short, Vista is definitely not ME, nor is it Bob.

One note: don't try to run it with less than 2 gig of RAM -- the difference in speed is dramatic. Also, Vista consumes considerable disk acreage. I found 100 gigabytes insufficient -- equal to about 80 gig on an XP machine. Now that I've put a 320 gig drive in my laptop, it functions as a true desktop replacement.
