I was an early adopter, I pre-ordered a G1 and have had it for about a year now. I really love hardware keyboards, so +1 for the G1 and for the Moto Droid. However, the article talks about a bit of lag here and there, which is quite irritating, probably the thing I hate most about android phones. Though, I do feel like the G1 was a competitor to the iPhone off the bat because it could do everything the iphone did, just a little slower =/
The iPhone is very well done, without lag from what I can tell. I suppose that's easier to do though when you make the hardware and software in the same place.
For now, I say the iPhone is still the best phone out there, but only because of the stuttering issues that Android phones seem to have. In a year or so, phone hardware will catch up with the Android platform and will run smooth as silk.
