GNS5870 with IPad 1 today BNE- PER and it was flawless for the 5:30 that it was in use. Sucked the crap out of the battery on the iPad though. Plugged in at 96%, had ozrunways running from about 15K on climb out and had 14% battery left on shut down- about 13% per hour I think.
No complaints with it so far.
