Tech Review

I'd have to say that Vista's gotten a lot better from the first time I tried it. And, when I say "a lot" I mean from frustrating and borderline unusable to pretty darn good and problem free. Service pack 1 (SP1) helped a lot. SP2 promises to do a lot more. Full reports are here and here. The benefits that I care about (or understand) are the bluetooth support, overall reliability, more efficient Windows Search, and the supposedly better battery performance.

I installed it without a hitch and everything seems to be working fine. Since I'm almost certainly not upgrading to Windows 7, this may be the OS configuration I live with for a couple of years.

I was too chicken to use the compcln.exe tool to clean out the old files, but I'll get to it later. Microsoft will probably release SP2 in a month or so. You can get it now from here.
