I never went to Android for it’s file system. Side loading was a neat feature but I didn’t/don’t get much use out of it. For me it’s the fact that I can navigate the system much faster than iPhone, the 3 buttons are always in the same place, and there are a lot more customization options.

I find iphones to be slower, very restrictive in nearly every way, and unnecessarily expensive. My employer likes it because it’s easier to lockdown, my wife likes it because it is locked down and her friends have iphones. The only things I see that iPhone has over android is how widely accepted it is in the US and it’s security.

I would jump ship if there was a decent third option. I hate that Samsung dominates the android market in the US. I hate their UI, the style of their phones, and all the bloatware they install that can’t be uninstalled. I loved my Sony phones but I had to switch to Samsung because US carriers don’t support Sony and Sony doesn’t support a lot of US bands.
