The elephant in the room for Android, from my point of view as a G1 user, is the woeful bluetooth support.
My previous phone, a w810i, supported a bewildering array of bluetooth uses, but the ones I found most useful were push/pull of my contacts and using the phone as a presentation tool.
Well hallelujah, android 2 platform highlights are saying that the new major version will contain
New BT profiles: Object Push Profile (OPP) and Phone Book Access Profile (PBAP)OPP is the one I want for managing and exchanging contacts, PBAP is for integrating with my car. Although I have to say it does this already.
I'm also pleased to see that there are a number of usability improvements, in particular for the soft keyboard, which I can't really use very well because of my phat phingers, contacts, email, and a digital zoom on the camera.
Oh and in case you were wondering, I think the ring volume is too quiet, and the battery life sucks. But since those are hardware issues I guess that after a couple of months of living with it Android gets a big thumbs up from me, and so is the recipient of the its-not-an-iphone award.
