I must say this year's release seems like the most underwhelming one yet (if this longer design that has been circulating actually is the real deal).
Last year was not very interesting hardware-wise, but for me the notifications in ios 5 were enough to keep things interesting (nothing revutionarily innovative, but still a huge improvement in usability nonetheless).
But this year? A longer screen might be a bit useful, although if Apple has same sweet UI implementation that improves usability it could be a hit. But if it only means slightly more content vertically, not so much.
Perhaps they have something really cool NFC-implementation coming that's just gonna rock? Who knows?
On the software side it doesn't look much better either.
Facebook integration? This should just have been a set of APIs last year instead of adding more clutter to all the share menus (you should be able to turn this off, printing too, Most people are never gonna use that, it just clutters the menus).
Maps? Nice but if I understand correctly (I have not tried ios6 yet) it won't show public transports anymore, just open links to apps. That is not a good solution, could have been a nice addition perhaps but I want everything to "just work", not having to open a bunch more apps to do what I could do easier before. Although given the added turn-by-turn navigation, maps might add up to +/- 0.
Siri? Barely counts, doesn't work yet where I live, and even if it did, it would probably only be connected to a a handful of American services that doesnt exist / nobody uses here.
Sadly, the thing that I am most exited about in ios 6 is the pull-to-refresh in mail.
End of Rant.
