The touchpad on the HP iPAQ hx4700 looks like an interesting idea.
(see http://www.synaptics.com/flash/navpoint_demo.swf )
However, when set in navigation mode (i.e. D-pad emulation), I think that there is a major problem:
When tapping, the user is never exactly 100% certain if the key event generated will be a cursor key (UP/DOWN/RIGHT/LEFT) or Action. It really depends on the position of the tap.
The problem I see is with using this in dialog boxes (e.g. to select an answer to a MessageMox). Normally, the cursor keys can be used to select a button or control, and the Action key to validate the selected control (e.g. to press the selected button).
It would seen to me that with the indeterministic approach of the touchpad, the user could very easiely cause the Action key event instead of a cursor key, which may result in selecting the wrong answer to a dialog. And this may have dramatic results (e.g. Do you want to Delete the file ?, Yes/No).
Another problem is with playing games. I doubt the new touchpad will allow multiple D-pad button presses, which is needed for many action games.
Also, on a Pocket PC, the "Cursor mode" of the D-pad seems very redondent with having a touch-screen... unless there are futur plans to have Pocket PC phones that have a touchpad but no touch-screen ?
MSFT often said that touch screen are not suitable for cellphones (which is why Smartphones don't have touch screens). But this touchpad could possibly provide a solution, which would allow phones to have the Pocket PC OS (instead of Smartphone).
What do you guys think ?
