a little plugin would be handy since it has SDK free for download.
this is not just a 3 button keypad but programmable so it can be set to display weather, ODBII info, or anything under any frontends.. prolly good for handsfree controlling. we just need people to write plugins for it
a good example would be:
button1: weather info
button2: email
button3: main menu (for frontend control)
then when phone rings, it changes function to:
button1: answer call
button2: ignore call/hangup
button3: has the caller id information
then once phone function has expired or finished, goes to original button assignments.
i see lots of potential but the price is a hindrance.
but it does add to OEM look too.
