I have been “dog fooding” Windows Vista for some time now. It has not been without pains. However, recent builds feel fantastic. I can finally run my screen’s laptop at 120dpi without any problems; the environment looks sooooo beautiful when in high-DPI mode (better than anything I’ve seen). The entire experience is really smooth and Vista is fast, really fast! I am no longer jealous of Mac OS for the almost instant return from standby, the boot times or the smoothness of the environment.

I don’t know anything about schedules but it’s my understanding that RC1 is not very far now.
