I miss sharing violations. Win7 is constantly telling me I can't move or rename something because it thinks some other application is using it.

What I recommend you do is make an exhaustive list of the apps you use on Windows and then figure out which alternatives there are out there. Personal finance; photo editing; time management; to do lists; outliners; note taking; games; drivers for you favorite gadget; etc...
