I just got the Bamboo and installed this software (a little nervous as it installs a kext, but I guess you've got to do that with these), and so far it seems fairly stable, and the features are great! I'm glad they didn't skimp on the mac version. And the only complaint I have is that this thing isn't entirely Universal. Everything is Universal except for the driver: "TabletDriverCFPlugin.bundle", hopefully this was just an oversight and will be fixed in a future release. -1 star for that for now.
