Cmon man, besides the fact that it's thinner, lighter, sturdier, has a higher density screen, a better screen technology, better graphics performance, better phone quality, a better camera, better media ecosystem, better apps, and will get timely & regular OS updates for several years what else have the Cupertinians done for us lately?
A list of barely perceptible (and some unproven) differences won't help Apple as the market share steadily trends away from them.
I like to keep it simple. Larger screen, faster processor, expandable storage, Flash, Google Navigation, freedom to from Apple's draconian grip...take my money Samsung!
It's no wonder Apple is suing. They know they're playing catch-up.
They are getting all of the profit share (and actually increasing market share slightly). In the long term, if you take all the profits, others can't compete unless they do so asymmetrically (make profit some other way). No one has shown that they are doing this yet -- Google and Amazon have plays, but I don't see how Samsung can do this -- they need to make profit from the phone, and they don't make enough to compete long-term.
