Android can do some things, like USB host, that other mobile OSs simply cannot match.
Actually Symbian, and I believe, Maemo already have been doing that for years. Now you know why Symbian people often get angry and how Android people are stealing their credits.
On the topic of this thread, I'd LOVE to have an iPod Touch phone. I know it's not really possible considering the small battery, etc, but I really like the form factor of the iPod Touch since it slips in and out of my pocket so easily and the screen is still big enough for my preference. I use the first Galaxy S (4" screen) and even that feel a bit big to me even though my hand is fairly large.
