I went to a Cisco conference with a colleague last week and had a chance to watch him use his iPhone quite a bit.
I have to admit that I am a little envious of how snappy and polished the iPhone is.
The Droid is so unpredictable. Sometimes you touch something and it pops right up, sometimes it takes a few seconds, sometimes it doesn't do anything and you have to touch again.
The iPhone's basic presentation is just better all around. Graphically, things flip and turn and tumble. I know it has no effect on functionality, but still, it just seems to be a level up on the Droid.
Yeah, I know that the iPhone has several years of a head start and the Droid is brand new. Hopefully we'll see it continue to develop. I wish there were some previews of things to come. 2.1 doesn't seem to be anything major.
Edit: Oh, and of course none of the iPhone users at the conference could get a signal, so that was fun.
