I'm seeing 'variable' battery life. It usually lasts for about 4 or 5 hours. Sometimes after charging it says "7 hours when in use"; sometimes it says "3 hours". It's slightly dependant on the screen brighness (turn it down, wait a few seconds and the battery life increases - makes sense) but it varies too much. Sometimes it charges in 2 hours, sometimes it takes 6 (always from less than 1 hour remaining).

I'd like to know where I can get a spare battery, too, if anyone knows...
