You know who this release is REALLY disappointing for? iPod touch users.
I know Apple always considered us the red-headed stepchildren of the iOS users, but come on. It's one thing to hold out on features for old versions of the hardware, but even the newest iPod touches aren't getting the good stuff on this release! There is literally no iPod touch on the market that will benefit from the new Maps app. All of the special features are iPhone and iPad only, so we're just left with something that's basically the old Maps app in a different skin, with public transit directions removed. And seeing as Maps is the only substantial feature of iOS 6, that's disappointing.
Of the other major features highlighted on Apple's iOS6 page:
- Siri: Again, doesn't apply to iPod touch.
- Facebook: OK fine, I'll give you this one, but it's not terribly exciting. Personally I don't even use it, but that's not Apple's fault.
- Shared Photo Streams: I guess somebody might use this? Maybe even find it exciting?
- Passbook: Now instead of separate apps, we'll have one. Hooray.
- FaceTime over cellular: Again, irrelevant on an iPod.
- Phone features: Irrelevant on an iPod.
- Mail features: Minor upgrades.
- Safari features: iCloud tabs might be useful. Offline Reading List too, especially on an iPod. Oh wait, iPod doesn't get this one? Well, crap. Why does the one iOS device that would benefit most from this feature not get it?? Don't try and say its hardware can't support it, it's a pretty simple feature.
- Accessibility: It's good they're working on improving this, but still, for most of us, that's not very exciting.
There are a few more features highlighted at the bottom of the page:
- Find My iPhone: As far as I can tell, the only difference is that it can now track where it's been. Useful when you need it, but most probably won't ever need it. This is really a feature of an App Store app anyway.
- Find My Friends location-based alerts: I don't know how many people use this app, but my guess is not many. Again, App Store app, not OS.
- Remodeled Stores: Really? This is one of the top 14 of the "200 features"?
- New Features for China: I'm sure Chinese users are excited, but it doesn't do much for the rest of us

I'm not saying these aren't useful new features, because generally speaking, they are. But the best ones don't even apply to the iPod touch, and of the ones that do… well when you're advertising 200 new features and these are the most exciting ones you can come up with, it's not much of an upgrade.
I'm pretty sure the only difference I'd see day-to-day is lack of public transit directions. I'm usually really positive and enthusiastic about upgrades, but this may be the first I skip.
