When you used the A5 for intrusion testing, did you use the built-in antenna, or did you hack on a RP-SMA jack for external? From what I read, the built-in ant (as is with many of these pads) was less than robust.
The only thing I can see these for is as DAPs with a limited selection of Android apps/games. There are already lots of more capable DAPs available at cheaper prices. Like I said, weird.
