Let's get feedback on whether or not Leopard has fixed some bugs... Freezing... Froze during account setup when the camera came on to take a snapshot for account. Played Wow and the game runs MUCH better under Leopard than Tiger (with updated gfx drivers), but froze twice. The game will stutter every now and then, but most of the time will continue on. Video... Some graphical tears. Probably still video card related. Overrall, the upgrade is worth it. The OS starts quicker and Cover Flow is awesome.
