i am looking into buying an inspire 1 to add to my S900.
What would people out there recommend for the mobile device/tablet.
Is it worth using the GPS map ?
I did try the lightbridge on my S900 and it failed miserably with signal loss and software issues so it was sold on. It was a shame as it promised a lot but did not produce any good results.
So what is the opinion out there on the inspire 1, does it have as many issues as the forums seem to make out. Is it reliable and supply good HD video transmission, finally what we the video and photo results like.
I do like the look of it but this time I want to do more research before I invest any further.
I look forward to any feedback particularly on the mobile device and GPS map question.

My wife and I love our Inspire 1!  She is my camera operator and I pilot the craft.  Regarding best tablet available we use two Ipad Air 2s and they work flawlessly.  Considering the issue with the most recent firmware and all the problems on the forums I have to admit that I have not updated my craft or RX at all since purchase (yes still running old firmware and I am still flying, not been shut down) and we have had very little issues pre, during and post flight.  Out of all my flights I have lost GPS once for about 5 seconds and had the drift that is associated with that loss.  Beyond that, no issues!  Picture quality is pretty much data driven, it takes 12mp stills and 4k video, whats not to like there?  Gimbal works really well, and the craft handles wonderfully in both calm and windy conditions.  HD video stream is very nice, and I have had no issues up to 2000 feet away.  Beyond that I start to receive warnings about signal loss, but honestly, I prefer LOS flying anyways.  GPS mapping, not sure what you mean there, the map on the app is basically Google maps and it shows an up-to-date relevence between you and the craft.  Autonomous flight and GPS coordinates are not working right now if that is your question?

Wish you luck in your decision, not easy to spend that much money, but I definitely recommend buying from Amazon as their shipping and return services are best I have ever experienced!  

I use an Iphone 6plus and found it better than black pearl and I pad.

iOS: Must be a7 chip, iPad Air or newer - includes iPad mini 2 w retina or newer....
Android: shield tablet

Many thanks for all of your informed comments particularly from precisionair
This is what the forum is all about, ok time to sell my sky hero setup tp pay for the inspire 1 and iPad 2

How about Acer A1-840? It has got quite good specs... Full HD display, 2 GB RAM etc..
Is there anyone, who has tested it with Inpire 1? Is the video smooth?

iPad mini 2 works well and is a good size for the controller.
