Battery

Today I used the N900 intesively (without using Wifi or phonecalls at all), and the battery charge only lasted about 12 hours. I was just gaming the very addictive Hex-a-Hop some hours, and that's it.

This is not very convincing, I would say. I know the battery charge duration is somewhat the same in all similar devices (?), but hey, it's year 2010. They went to moon in 1969, they will fly around the world with solar energy only, etc. I would expect something better...

Why all the devices could have some small solar panels on them? Even if they were very ineffective, something is better than nothing.
