Solar powered keyboard

A wireless solar paneled keyboard might seem like a really great idea at first look - no more fiddling with batteries and having it get confused every couple of months.


Until you hit on the slight flaw in the scheme - solar panels work on sunlight and computers - especially desktop computers get used indoors. Oops. My question is - did they really not think of this when they built the keyboard, or did they think "Hey, everyones saying they want to go green these days - how can we cash in?"

Was it stupidity or greed? I'm not sure which is worse.
