Since the iPad debuted a couple of years ago, people have been trying to turn it into a low-cost, lightweight replacement laptop. Adding a Bluetooth keyboard is a good start, of course, but then you’re stuck lugging around two separate items. That’s hardly an argument for being able to simplify your life with an iPad. Or is it? Logitech’s Fold-Up Keyboard turns your iPad into a Transformer, letting you use it tablet-style, or with a full-size keyboard when you need a productivity boost.

Few things are as handy as an iPhone battery case—binder clips, Swiss Army knives, and the iPhone itself. But most iPhone battery cases add bulk, and don’t always have juice when you need it most. Third Rail takes a novel approach by keeping the case and battery separate. Your iPhone stays in a sleek, attractive Slim Case that adds practically no bulk at all, just a centimeter or so at the bottom. Flip it over and you’ll see a contact strip of three gold rails—that’s where you’ll snap on the 1.4-ounce, 1250mAh Smart Battery. Micro-USB in and out ports let you charge the battery from a computer or USB power adapter and juice up other gadgets that charge via USB. If you want extra power, you can buy additional Smart Batteries for $59.99 each, and when they all run dry you can stack them on the Slim Case to charge everything up at once.

Imagine every feature you could ever want from an iPod dock. Go on, make a list. Ours includes AirPlay, solid sound quality, an iPod charging dock, and a reasonable price tag. This is good news for the iW1, which includes all these features and a boatload of others we didn’t even know we wanted.

A good pair of headphones can make you feel the music instead of just hearing it. But any hip-hop producer can drop 808 beats so low that you feel them in your gut, and any headphone manufacturer can artificially pump up the bass to make their tiny speakers sound bigger than life. That doesn’t mean your headphones are good—it means you’re not listening to the music as it was produced and leveled. The Shure SRH940 headphones aim to balance the scales and change the game.
