It appears that Microsoft is going to release an other intermediate Windows Mobile version before version 7. Microsoft now says that following on the heels of WM 6.5.3 (just released), will be WM 6.6.

One of the interesting features discussed is adding support for Capacitive touchscreens. Up to now, almost all Windows Mobile devices have had Resistive touchscreens. Why does this matter? Resistive touchscreens are more suited to using a Stylus, which Capacitive touchscreens require a finger (in fact, they won't work with a stylus). The iPhone and iPod Touch are examples of Capacitive touchscreens. Another difference is that Capacitive touchscreens support multi-touch, while resistive screens do not.

Many users prefer the responsiveness of a capacitive touchscreen, and they are perceived to be a 'superior' technology. However, is Capacitive a good choice for a data collection device? It would certainly not be a good choice for applications requiring gloves. It will also require changes to the way applications are designed, as on-screen elements need to be larger to support less accurate finger-press as opposed to a stylus. However, it opens the door for more gesture-based elements, such as flicking lists to scroll.

We will see if any of the Data Collection device manufacturers choose to release new models with capacitive screens in the coming years.
