Despite the clear advantage of a physical keyboard in a business handheld, Apple's iPhone is obviously making just about everyone in smartphone land a tad uncomfortable -- even if they won't admit it -- which means we could be seeing some new BlackBerry form factors from RIM in the coming months to keep consumers interested. Of course, there's no telling if those new form factors will have a tilt-and-slide mechanism, or multitouch, but these here patents are certainly a start. The tilting mechanism aims at giving users the best of both worlds: a true keyboard and a big display, but the multitouch mechanism is interesting as well, and uses a different tech than the capacitive touch in the iPhone. Only time -- and hopefully Mobile World Congress next week -- will tell if these patents are going to be put to good use (hopefully as a team) in your next BlackBerry, but we're certainly intrigued.
