When the iPT first came out, there was no software in place for Contacts, Notes, etc., but a couple of free (and one $20 paid) software updates since then (we're now up to V. 1.14) have added those.

I can't wait for them to integrate BT and the A2DP (stereo headset) profile; I've got a Jabra adapter that lets me do that (as well as seek between tracks and pause) but that's an addon and internal integration would be killer.
