As far as I'm concerned you've just described Android or Windows Phone for that matter. Come on people let's have something a bit more original than the above. Whilst that claim may have had some merit a few years ago that really is no longer the case.
This is why so many people have a go at Apple users, they constantly trot out the same outdated mantra time after time.
OS wise there's barely a pin to put between all three.
Whilst you don't have to justify your purchases to anyone why not dispense with all the guff?
I agree with most of your points, but I disagree with the first sentence here. WP I agree totally, Android on the other hand still has a long way to go to be a proper, smooth, unified OS. This is coming from someone who's spent the last 18 months with an HTC One.
I'm now trying to decide whether to go back to WP and a Nokia 930 or go for an iPhone 6. Just depends if the screen doesn't let it down when I go to look at it...
You'll never "win" against certain members on here however, they are well and truly entrenched and have been for a number of years, just like the more recent Android entrenchment.
