RIM has just filed a patent application for a display that combines the best of both worlds. These screens will have the smooth, fast touch like a capacitive model with support for multi-touch and gestures, and the resistive model's ability to make precision data entry with the use of a stylus as well as allowing for those with long nails and covered hands to move objects on the screen. The one thing that the combination screen doesn't fix is cost. The hybrid display will remain expensive which limits its use to high end touchscreen models. One cellphone manufacturer has already brought something new to the market. Samsung's Jet feature phone (smarter than your average bear, uh, smartphone) uses a technology called R-Resistive which is supposed to combine the best of capacitive and resistive screens.
It is not known how far along RIM is in terms of actually employing this hybrid technology. It could be something that will debut on the BlackBerry Storm 2 or it might just have to wait for another high end RIM model.
