+x KimW - 11/18/2021 9:11:40 PMI use Lenovo M8. Perfect size, very long battery life (have seen +7 hours flight time with SD without needing external power source) and low price on the plus side. A bit slow for planning in the device, but have had no issues in flight using internal GPS. Use my phone as hotspot to get data access on ground and if needed in air.I have looked at iPad but just don't find price value reasonable and seems there is issues with battery life and overheating, as high performance in small formfactor has it's drawbacks.Hope you find what works for you.
