Don't worry, I'm totally patched to current. The day SP1 was available I loaded it on the laptop once I isolated which driver was in the way (didn't like the sound driver, fixed that right up) because it also fixed some GPO stuff that was making life weird on the AD domain for me. The desktop at home never had any driver conflicts at all. I've never had a single stability problem with Vista. The only blue screen I've seen was due to a bad DIMM. I'm actually kind of shocked at just how stable it's been. I know there are some people who've had serious problems with it, but I haven't seen any on the Dells at work or on my custom built box here (I'm home now), but all these machines are using hardware that was released after Vista's RC and beta stages.
