Since I literally just changed the batteries on my own wireless keyboard earlier this week, it occurred to me that more of you might want to know about the Logitech Wireless Solar Keyboard K750, which was introduced late in 2010.
Retail-priced at just under $80, the keyboard uses solar power -- actually any form of light -- to keep itself charged up. The company said that it can go for up to three months in darkness without being charged. A solar app provides the information you need about charge levels and such.
The keyboard is about one-third inch thick, and it is made out of PVC-free materials, further enhancing its green technology credentials. It includes 2.4 gigahertz wireless, along with 128-bit AES encryption, as well as a unifying receiver that you can use to connect up to six Logitech mice or keyboards. Another thing to note: the product carries a three-year hardware warranty.
Sadly, if you are Macintosh user like me, you're out of luck: The keyboard requires either Windows Vista or Windows 7.
