Are you.. nuts...
First of all, the 3GS is a much smoother and more reliable experience than the droid, and the UI on the iPhone is unmatched. My sister has a Milestone (Droid in Canada), and it's really not up to par with my iPhone. Android's UI is hideous, lacks animations, and is completely inconsistent. You can put on the green-coloured glasses all you want, but please don't distort the truth. The Droid is a fine phone and I have nothing against it, but what you're saying is sooo not true.
Second, the iPhone makes calls just fine, some people have zero issues with AT&T, the complainers will always seem more common because when you're having a great experience with your iPhone you don't rant about it. Not to mention there are other people living in other countries, too. It's not only Americans that use iPhones, and we Canadians have 5 great carriers to choose from, all of which have great coverage.
If you are all about to each their own and what-not like you claim to be, try not to insult the iPhone so much because if that's all you're going to do I don't see how you can continue to claim to be so neutral about it.
