Let's face it: when Android first officially dropped, it was ugly as hell and not exactly designed with non-techies in mind. But as we've seen in the past 3 years (and a few months) since then, things have come a long way (albeit gradually at first) - the look, feel, and usability of vanilla Android became a major focus in the last year or so, especially with Gingerbread (2.3), Honeycomb(3.0), and Ice Cream Sandwich (4.0).

Again, while it just plain looks a lot nicer now, things are much deeper than what can be shown in a screenshot.
