The above phrase has never made sense to me, doing something just because you can or even climbing a mountain because its there.
But in the Technical sphere the above picture is a thing of beauty, Nokia N9 Charging off the Nokia N900. Technical hardware not conforming to the norm. People doing what they want with their devices, dare I say it "Thinking out of the Box", One of the reasons I've always loved this community and these devices.
Note: The Nokia N9 does not support USB host mode at the moment but work is being carried on it on this thread at MeeGo.com
Now please, lets not spoil the moment with words. Let the picture do the talking.
