I guess in many aspects, the Sole Mio mouse is pretty much like a reptile that needs to bask in the sun. Why so, you ask? The answer is pretty simple – it recharges itself as long as there is some semblance of sunlight in the vicinity. I suppose those who sit beside the window at the office are the ones who benefit greatly from the Sole Mio, but as for the rest of us, why don’t you just stick to a wired mouse that draws power from the computer directly? Then again, you have a very good excuse not to get any work done during those cloudy days if you’re using the Sole Mio mouse.
