Ah, Texas barbecue. That's a topic of some interest to me. I know I'm coming to this conversation late; but here are some quick thoughts on what's been said.
I'm going to have to agree with some of those who have questioned SteveZ's characterization of Texans' brisket fixation. While many Texans love brisket, the stereotype that they love only or primarily brisket is false. Robb Walsh attacks the stereotype in his excellent "Legends of Texas Barbecue," laying out some of the historical and demographic forces that led to the incredibly diverse barbecue scene in Texas. In a nutshell, you have black populations (largely in East Texas), German and Czech immigrants (particularly in Central Texas, along the cattle trails), and Mexicans (West and South).
A lot of what SteveZ says about Texas barbecue (generally) is more true of Central Texas barbecue, where (a) barbecue grew out of the meat markets along the cattle trails, meaning beef was king, and (b) the Germans and Czechs brought their sausage-making skills to the table. But, even within that region, there's a wide diversity of meats--brisket (fatty and lean, which is a distinction that should be more widely made), spare ribs, beef ribs, lamb and mutton ribs, shoulder clod, pork loin, beef sausage, pork sausage, venison sausage, hot links (including the famous versions from the "sausage capital of Texas," Elgin), chicken, turkey, ham, et al.
Go a little farther west and things change. Instead of indirect heat from post oak, you get more direct heat and mesquite smoke. Though brisket is present, it's not as critical as it is in the region described above. Cabrito becomes more common (and quail and dove can sometimes be found). (Barbacoa, which some also consider a form of barbecue, continues to spread from the Valley, including pork, cow, and Guanajuato-style goat head.)
Go east from the German/Czech Belt and the black influence pushes pork to the top of the list. Hickory and pecan are the more common woods. And meats are often finished wrapped tightly in tin foil to steam them to tenderness. While a sloppily sauced spare rib with meat falling off the bone would be inexcusable in Central Texas (where the ideal is a dry rub, if any, no sauce, and meat that's tender, but firm enough to just cling to the bone), it's the preferred form in the piney woods of East Texas. Rib sandwiches and hot links are the way to go out there (and pulled pork isn't unheard of).
Go further north and hickory becomes the wood of choice. Meat selections include almost all of the above (with the exception of cabrito, which is only available in a few Mexican joints, and is usually more "al pastor" than barbecued), but will also include the occasional bologna or salami. If there is a clear meat preference in North Texas, it would
not be for brisket, since most places up there do it poorly.
All of these are
still stereotypes--just less inaccurate ones. Exceptions abound all over the state. And we're not even talking about some of most commonly ordered items in bbq joints: sandwiches, a category in which there's also considerable variety. Or barbecued baked potatoes. Or barbecued Frito pies.
There are thousands of barbecue joints in the state of Texas, spread over areas that differ geographically (resulting in differing economic forces affecting choices of meat, wood, and cooking method) and demographically (meaning wide differences in tastes, traditions, and expertise). And I doubt that most Texans--even those who fancy themselves barbecue connoisseurs--have eaten at more than a dozen in their respective home towns. But even if they'd been to two hundred across the state, that's a drop in the bucket. Making generalizations about a market that big is a dicey proposition.

PS Rob, I just wanted to apologize for the shabby treatment you got from a couple of Chowhounds (one of whom is consistent problem for the moderators, so don't feel singled out) before your recent trip to Austin. Texas hospitality is generally much better than that.
