I just plugged in my MacBook Pro after short usage in the garden on battery.
I was going to start a new thread, explaining my current predicament, but I saw this topic at the top, so I'll post here instead.
So far, I've had two freezes, one was while watching a low quality avi file in VLC in OS X, and the second was yesterday while 'watching' the intro of Call of Duty Modern Warfare 2.
I unplugged the MagSafe and USB devices and brought my computer outside to the table, while grilling. I was doing some light browsing, using the intel graphics card, and iTunes running in the background.
Suddenly FireFox went stopped responding and it showed that loading mouse cursor, I tried to hide the dock, but it got stuck. Out of anger I closed the lid and left it inside. Later I checked if it will still stuck, and it wasn't. I could use FireFox and the dock was working fine, but I couldn't click in the top menu at all, and it had the loading cursor there... Once I plugged it in the MagSafe, everything was fine, as if nothing had happened.
I'm rather unhappy was the current problems I'm having, after paying this much for a laptop, I expect there wouldn't be any problems.
There's also a rather annoying bug with the option key when I boot into windows. I cannot have my ethernet cable plugged in when doing it. Or nothing happens from holding down alt.
Edit: Apparently, now my dock has lost it function to magnify when hovering over it. Even though the preference for magnifacation is ticked.
