RE: Crashes, I have had around 9-10 totally random kernel panicks with LION in about 4 months, when i was on Snow Leopard I never had one, have run ONYX and done a hardware test and it says everything's ok, but still get crashes.
Got to say really disappointed with Lion. Have had kernel panick with just ical mail and chrome open, running just one tab(BBC). Was thinking of doing a format and reinstall, but will probably wait to see if Mountain Lion cures the issues
