UTR makes a good point. I'm just about over Apple. My iPhone 6 is a disaster and the once excellent Apple support has turned mean. When they replaced my last bent iPhone 6 (which had never been in a pocket) they tried to get me to agree to revised warranty terms which are illegal in Australia.
And the iOS has become slow & bloated full of games & fitness apps.
But, the interesting question would be whether I would go back to Jepp Flite Deck if I returned to a Windows device. I think its better than AvPlan or OzRunways in flight, but let down by its flight planning function.
