I was thinking the battery myself too. I have understood that N900 charges itself when plugged to a computer with usb at least when you use it as a mass device. But so is it that it doesn't charge when used as a monitor or keyboard? I mean that if the stick computer could be charged from a different port than from which it is connected to a N900 then there could be a charger for that and N900 would be charging itself through the stick computer. That is the way I thought it should work. But if it is absolutely not possible shoot me down before I fly to the sun and get my wax wings melted. I'm not a rich man so dobn't wanna put my money on something which won't carry.
