ZNet blogger Heather Clancy has declared Logitech’s solar keyboard “Green Gadget of the Week.” I wouldn’t disagree. Logitech’s Wireless Solar Keyboard K750 is powered by light—indoors or out—underscoring its “green” credentials. Eliminating the potential of getting caught with dead batteries and no replacements at hand is an attractive attribute, but there are plenty of other reasons to like the K750.

I fancy myself a bit of a keyboard connoisseur. Or, maybe not. Maybe I’m just picky. Regardless, the bulk of my interaction with the computer is through the keyboard, so it’s very important that I find one that’s functional and comfortable. To that end, I take a look at two very different models in this review: The Celesta from Moshi and the Ci70 PhotoSync Desktop Set from Kensington.
