Rick, its obvious Apple have run out of ways to differentiate, so they've taken a page from Microsoft: Its cheaper to litigate than to innovate. Or "If you can't beat-em, squash 'em"
Hence the bogus patents over something like curving the edges to make the product look slimmer (something taught in design schools for over 50 years ... how long ago did they remove the [very practical] running-boards from cars in the name of appearance?)
Let's see: larger display, NFC (like my nearly year-old Google/Samsung Nexus, precursor to the Galaxy-IIIs), and quad-core CPU, which is current "generic" processor power, as in the Freescale i.MX6 ... wow Apple is almost catching up to Samsung's old products, while Samsung and Google/Android are preparing to release the next generation products that are 2 gen ahead of what Apple is chasing. Wish I had cash to sell-short on Apple stock, except the price will remain high for a decade after they peak (which they have) just like Microsoft.
Maybe a bit off beam, but just saw that Apple is suing a Polish on-line supermarket chain for having the gall to use the addrees A.pl. If any Polsh retailers of green or any flavour apples wants to countersue , I will contribute a few Zloty's towads the legal costs
