I owned a BlackBerry Curve, a Motorola Q (my favorite keyboard ever), and a the truly awful HTC Ozone. But I’ve never wanted a phone as much as I wanted the Dell Venue Pro, the Windows Phone 7-powered device that had both a big, beautiful display and a slide-out portrait keyboard that was incredibly comfortable to type on. The Venue Pro died before it ever really breathed life, but a tiny company called Typo is trying to revive its essence. The pitch is simple: the Typo Keyboard case adds a BlackBerry-style keyboard below your iPhone’s display, so you get everything great about the iPhone, except instead of typing on your screen, you can type on a tactile, clicky keyboard.
