And then there's the fan. Yes, this tablet has a fan, and it's almost always running. Granted, this is an x86 device. But so is the MacBook Air, which doesn't even have a fan has a miniscule fan that basically never runs. Microsoft talks a big game about how Windows 8 is going to be optimized for any device, but in its present state it seems to have some serious performance issues. Both the demos yesterday, and my personal experiences over the last twelve hours, were riddled with system freezes. Again, I know this is a developer preview, but it wasn't encouraging.
