The Logitech K750 Solar Keyboard...so far it's great.

For years I used stock mice and keyboards until I realized that the good ones do make a difference.  I recently purchased the Logitech K750 keyboard.  I did so for two reasons, it is wireless and it is solar (no more batteries).  It powers with any kind of light, not just sunlight.  In the two weeks I have have it, it truly is a great keyboard.  Most surprising to me is how sturdy it is.  Most keyboards do not really have any sturdiness to them, they feel like....keyboards.  This one does not, it is very firm and the keys are great.  A bit pricey at around $50-$60, but worth it.
