The Sidephone, meanwhile, takes a modular approach to customizing the hardware to fit into your life. A screen takes up the top half of the front fascia, while the bottom has room for swappable modules. That might make this desirable to gadget nerds who aren't even necessarily in the market for a less engaging phone. The included T9 keypad and 2.8-inch touchscreen should be enough to get around those. US$299 nets you the phone along with the standard T9 keypad, and you can additional tiles for $29 each.
