Missed this, soz
I'm fully entrenched in the iOS system and way of doing things which does make my choice easier, I admit, but I genuinely think the iPhone is the best phone for me. Above all else, I rate response as the number one feature on a phone, and the iPhone has and always will trump anything else on this simply because of the way the OS prioritises things. Try them side by side in a shop, and you'll see with ease that the response on the iPhone is quicker than any Android phone.
Of course, I appreciate that this doesn't matter to everyone and fully understand why people don't like iPhones (some reasonable, some just anti-Apple), however if a device cannot get the very basics such as interaction right then I'm not interested.
This, sums it up in a nutshell.
Back 3/4 years ago when I got my iPhone 4 - It was unbeatable in terms of response, other phones Sony, HTC, Samsung etc, were all quite - lets say laggy when it came to scrolling through apps etc.
Now to be fair, that was 4 years ago, and phones have got considerably better now, and I haven't really tested anything else. - I for one am no apple fan boy, wouldn't get a mac/imac unless I was seriously into photoshop etc. and I HATE itunes with a passion.
What Android has over IOS is free roam to 3rd party apps/software/configs etc - Iphone is locked down unless you remove the lock down, which many people would prefer not to do.
