Logitech presents the Case+, billed as the only case you'll need for your iPhone. More than just a mobile accessory, the Case+ is a system made up of add-ons that attach magnetically to the exposed metal back of the primary case. Those additions comprise the +Tilt, featuring a kickstand and cord keeper; the +Energy, an external 2,300 mAh battery that's rated to double the iPhone's battery life; +Drive, a secure mount for car window or dashboard; and the +Wallet, which provides a place to keep all your everyday essentials -- phone, credit cards and cash -- without carrying a wallet. The Logitech Case+ is set compatible with the iPhone 5 and 5s and is set to launch later this month for $200. Pre-order it here.
