I've used it a couple of times myself as second ID, or as the one that I grabbed by accident.

Never had anyone bat an eye. People who "recognize" the ID either deal with ID every day, or have one themselves (and thus generally have the good sense not to make a big deal of it) -- nobody else really recognizes it for what it is.

I now carry both a TX DL, and a TX state ID card (I also carry my passport card, but I never use it--I just find it more convenient to keep it in my wallet while I keep my passport book in the safe).

I have found having the separate TX ID and TX DL quite handy on a number of occasions -- like those times that I have to leave an ID with security to get a temporary building key and such. Just something to consider since it's only a few bucks extra, and one more form next time you're at the DPS office.
