Lets be fair here. A lot of stuff Samsung packs in there is utterly useless. Even their NFC isn't all that great. Just because they were first to add something doesn't mean it's necessarily better.
On one hand Samsung does right with removable battery, USB port, and MicroSD. On other they have botchy software that is bloated and updated barely once a year. The Iphone is missing some of those other things but the design and software are tightly woven together. Both have plus/minuses.
Truthfully, for me, if it weren't for the integration of Imessage and other features between the whole ecosystem (iphone,ipad, macbook) i may have given Samsung/Android a go.
As it is i am firmly committed to Apple for better or worse.
