Best bet when you are trying it for the first time is the carry a paper copy in your bag as backup. Also, remember to alert the WTMD operator who will take a look at your PDA, then have you put it through the x-ray.
Other than not longer having a piece of paper to store/throw away when I'm done, I'm not really sure if the new technology benefits me much.
If you print a copy of the boarding pass at the airport I think it may invalidate the digital version.
I have tried the PDA check-in a few times and for safe measure I printed my boarding pass beforehand and the PDA check-in did not work. Other than that, it's worked fine for me at IAH.
