Just curious of what other peoples opinions of W7rc are from the physics nerd point of view? So far, I think its great and I have yet to have any compatibility issues. Matlab 2008a runs great on it along with Comsol 3.5. I don't know if its just because its 64-bit or what but so far I definitely like it over XP and Vista. The application and program management is really nice too plus the whole interface looks just wicked awesome! It's still a bit of a memory hog though. With a fresh install I get 660MB on boot, compared to 136 for XP, 890 for Vista, and 88 for Ubuntu. Theres a lot of room for slashing though, I'm hoping to get it down to ~350ish for the OS alone which seems reasonable considering the pretty interface and features it has.
