I did a simple upgrade from Panther with the disk, no backup was BRAVE... (hey I'm a grit your teeth PC guy, upgrade windows and close your eyes..) FCP 4.5 works fine capture and edit no prob, will advise on out put to tape. New mail app very streamlined, AVID XP has a problem, the only way out is to crash the app after a save, on quit you get the full on lockup beach ball. Tiger seems to prefer a shutdown instead of a restart after pulling the PB off it's block and going mobile. Lost my mouse and all my USB's (dongles) and aborted startup (grey screen) on two restarts. Powered down and all comes back. Otherwise, Safari seems to snap. Mail is good and less obtrusive, esoteric apps like blackberry plug in for calendar work fine. Will advise
cheers h
