FWIW, I went ahead and sent mine into Huntsville (the repair shop that comes up on the form) via second day air. So we'll see if I just wasted $20 on shipping and insurance or not.

Based on re-reading this thread, I did a recalibrate, and realized that the touchscreen is working, but that presses on the device's right side aren't getting registered all the time. So it looks like it actually is the same problem.
