I'll add a different spin for you...most would stay out of Dallas school district, not dallas county, different things.
A LOT of people live north and drive south every morning to get in Dallas and then north again for home.
anything dallas west and over will be a nightmare anytime there is a concert or a game or such, then with people driving home that way.
If you don't live where you work you'll want to consider this for the freeways.
If your husband works in Plano, I wanted to add other areas that weren't mentioned yet that you may want to consider.
I would also personally live in any of these areas.
(Garland, Sachse, and Rowlett that fall in Dallas County Gisd- Sachse, Collin County is Wylie Isd and Rowlett, Rockwall County is Rockwall Isd) GISD I am familiar with and has a great music program and has choice of schools. you can basically pick any school in the isd for your child to go to and live where you want if you choose, but, if not the "zoned" school, you will have to provide transportation.
the areas of Parker, Sachse, Murphy, Wylie, Garland, & even North Rowlett area...all a quick drive up george bush/190 to Plano. Now, with 190, people head up it in the morning and back down/around to Garland/Sachse/Rowlett at night.
They have just started to build the eastern extension of 190 from Garland thru Rowlett to I-30 and it is proposed to be finished in 2011.
Established or older neighborhoods will not have hoa's, good in some instances, not in some others. Newer subdivisions have hoa's, some with amenities and some with none. there are areas of not so nice everywhere, busy hubs, and places with a rural feel still in each area. It just depends on where you choose.
