I have an iPad 2 with WiFi and cellular cabable but I've never used the cellular feature. At the time cellular capability was required for onboard GPS services. This iPad is still serving well as a GPS moving map solution in the Warrior. I do not use one of the paid GPS/EFB services, but something which gives basic GPS and flight Planning features and runs on the FAA free digital raster charts. The iPad2 only has 64GB of storage of which I am using less than half. I am thinking it may be time to upgrade to a newer iPad. I cannot stomach spending $1000 for a tablet. I'm looking at the lesser iPads, but most of them are WiFi only, which would be fine if they supported both onboard GPS and BlueTooth. Which currently available models fit the mission?
