Microsoft Research is expecting not, as it's already working towards integrating force-sensing technology that will enable gestures to twist on-screen imagery without crafting UMPCs out of flexible material. Essentially, the gurus behind the idea feel that implementing said tech would "turn an otherwise passive component that just holds the device together into an active input surface."

In the future, it's likely that auditory cues would enable users to know when they've applied enough pressure to cause a change, and of course, they expect it to work hand-in-hand with existing human-computer interfaces. Yeah, who needs keypads these days, anyway? Share your comments....
