When Logitech first introduced wireless peripherals, we'd be lucky if our alkaline cells lasted a week, but these days the firm's low-power mice can go months on a charge. Now, the company's taken the next logical step, and made a solar keyboard. With an ultra-slim 1/3-inch profile and a full slate of laptop-style chiclet keys, the Logitech Wireless Solar Keyboard K750 isn't your average rack of buttons to begin with, but the ambient light solar panels installed on the top of either side should mean you'll never need to plug it in to recharge. That's not a claim we'll be able to test easily, of course, as the company tells us its low-power integrated circuits can theoretically run for three months even if you leave it in a dark desk drawer. It uses the same 2.4GHz Nano Unifying receiver as several other Logitech wireless products, too, meaning you'll only need a single one of your netbook or set-top-boxes' precious USB ports. That's often a concern on MacBooks as well, though you can see from the prominent Windows key this particular product doesn't quite have a Mac-friendly setup.Though we're obviously far away from being able to tell you how the solar panels fare in normal use, we're typing up this article on one of the boards right now. So far, we're loving the flat, firm feel of the slab and rounded finger-friendly indents on each key, though the QWERTY layout's actually a little cramped for our tastes. We'll let you know how it holds up over the long haul. Find it next month for $80, though, if you're already sold.
