Heh the only one missing from that list in my small town is a bookstore; the Walmart book section doesn't really cut it.

One thing people can get confused on is that density doesn't necessarily go hand-in-hand with mixed usage - you could have relatively low density areas that are extremely mixed so there's always basically everything within 15 minute walk, and you could have very high density apartment buildings with nearly no services to speak of.

Suburbs are especially bad at this because they segregate the living and the sleeping areas far apart from each other (but relatively short by car).
