That's actually primarily for phones. For tablets you're supposed to use sw<x>dp. So, add sw600dp and sw720dp to your list. Now we're talking about 8 logical resolutions to support. And the bigger issue, as another person pointed out, is the fact that a _lot_ of the new APIs aren't backported. So you end up having to target the lowest common denominator API version, which is almost certainly two years old. Contrast that with iOS. The latest version adoption rates are something absurd like 90% within the first month. You can actually take advantage of those spiffy new APIs without having to worry about limiting your audience. The limited set of resolutions is icing on the cake... far less to worry about.
