Why, exactly, do you a wireless keyboard? Using Corsair's newest effort, the $99.99 K57 RGB Wireless Gaming Keyboard, I found myself asking that question. The untethered version of the company's $49.99 K55 RGB Gaming Keyboard costs about twice as much and delivers the same features, only without a cable. Some of those features are admittedly nice, including dedicated media controls and a row of macro keys, but all that key sprawl that these extras demand makes the K57 RGB less handy as a wireless device. It's a big keyboard; you won't want to travel with it or park it on your lap. You may want a wireless board for other reasons, of course, but the premium that the K57 RGB levies for that trait makes it a tough sell, at least at its list price. No Wires, But Strings Attached Despite that harsh value assessment, the K57 RGB is by no means a bad keyboard. In fact, among under-$100 non-mechanical keyboards like its K55 RGB wired counterpart, it's a solid effort. This is a full-la...

Wireless, but too large for lap use; Squishy key feel; Pricey considering feature set and non-mechanical keys; Hard wrist rest isn't comfortable over long stretches
