I have a TI calculator that has a solar cell. My dad brought it home in the early 1990's. It has been working ever since, which is pretty good for a thing that originally cost only $30. It uses Anylite solar-cells so that it can be usable in most light settings.
It's just nicer to not EVER have to plug it into your computer or to a wall.
The biggest issues would be placement, and then the fact that they'd have to be pretty big. But these devices use little energy to begin with, so I think if the research was done, they would make it happen.
