I'm on my 3rd crash today in 7 weeks of new MBP, and I mean total hang up! not even a mouse cursor, with physical power down as only remedy At least the last two times have been using YouTube in latest FireFox. Hard crashes like that were once a year events with my prev 2.4MBP, I hope this isn't a sign of things to come for Apple! Anyone else seeing issues like this? I'm up-to-date with patches and versions of everything.
