Newcomer SnapKeys used an event at CTIA to show off a fresh approach to keyboards on tablets, including the iPad, that only uses thumbs. Ideally, the SnapKeys 2i system would not only make typing on a tablet easier to use but promises a very intelligent auto-correct system that lets users type faster than they would otherwise. Find out in our hands-on below whether it's ready to go or if we think it might face some challenges to adoption.
