i haven't had any full crashes yet, has been very stable, possibly cos the machine came with it ? but swipes etc are still causing me grief, and others it seems :
Multi-touch quirks. Apple introduced new multi-touch gestures in OS X Lion, which means a lot of the gestures third-party apps were using for basic navigation are now broken, like back and forward in Chrome. Also, I’ve had more trouble using gestures like two-finger back and forward in Safari than I ever had in Snow Leopard, because the gestures appear to be more sensitive. I love swiping between full-screen apps, but why isn’t that a four-finger action by default, leaving three-finger gestures to manage back/forward actions system-wide (especially in Finder)?
