* inbuilt speakers for use as a speakerphone or a tiny tiny stereo for playing podcasts of In Our Time as I fall asleep at night.
* just beautiful user interaction and graphics. I don't think any other gadget makes me say "oh, cool!" quite so often.
* using Safari to Google for tourist locations in
* "visual voicemail" - it's just a list of my voicemail messages that lets me listen to them in the order I want, but that's actually very useful.
* unlike my Treo, the call quality is not at all bad.
Things I wish it could do that it can't, yet:
* recognise addresses on web pages and turn them into links to open Maps.
* stay un-smudged for more than five seconds. I guess that's the price we pay for a multitouch interface.
* really know where it is, on Maps. It's usually out by about half a mile. (Mind you, that's often close enough to be useful).
Best bit: I managed to get a prepay account from AT&T, and avoided having to sign up to their 2-year contract. When I come home for good, I'll be free of AT&T entirely - yay!
