exactly, man, but remembering to USE it, that's hte challenge.
I've had to remind people about it, before. As for where to check out OS X, couple options, depending on your locations.
use the apple-store finder on their site, if there's one near you, that's where I'd suggest to give a powerbook a test drive (check out the ibooks, too, easier on the pocket, and VERY nice). If not an apple store, try a comp-USA, Frys electronics, or your local mac shop. apple should have listings for shops in your area, so that's where I'd start.
