Gadget Ogling: Smarter Smartphone Gaming, Modular Watches, and Vampiric Charging CablesI don't enjoy playing complex games on a smartphone. Using the screen as both input and output device makes matters complicated, so I tend to steer clear of any game that requires more than single taps or simple swipes. There are a number of game controllers around for smartphones, however, and the Satechi Wireless Gamepad, a Bluetooth device, is compatible with iOS, Android and Windows phones.
