I'm actually in US, but in my experience Apple devices are a minority. I agree it can depend on population and area you are in. I wouldn't expect it to hold steady. Apple aren't interested much in innovating in the OS itself. Neither is Google for that matter - Android is pretty stale too. It means that next coming innovative contender can disrupt the market.

Not sure whether EU dictates such thing as common ports, but I wouldn't be surprised if they do.
