I'm probably commenting ironically...
Near (or in, depending on how you interpret the map) White Rock is an area called Lakewood and it's probably the only neighborhood I'd like to live in if I had to move back to Dallas. It's got lots of mature old trees, it's at least partially walkable (compared to the rest of the city) and it has much more of a "local" feeling than a lot of Dallas. There are some GREAT places to eat (Legal Grounds is a coffee shop/law library with outstanding whole-grain banana pancakes, for example) and the Lakewood Theater gets a lot of acts that bigger stages won't carry. I've seen Richard Thompson there a couple times.
Lakewood is great...but more expensive than Southlake...can't find a decent house under 500K
I would recommend Plano, Frisco, The Colony, Lewisville, Grapevine, Carrolton and if you don't mind the drive Mckinney
