I dunno, how crummy the App Store has become is a perfect example of this. The App Store is one prominent way they make loads of money and build loyalty to the ecosystem, and yet it is a shitshow on IOS6...the responsiveness is as bad as I've seen on non-iOS software, but for me, the two really inexplicable failures are:
1. the use of modals to show individual apps on the iPad. So if you get to an app page and accidentally touch outside the modal, the app page disappears and you have to go back to Safari to find the link that brought you there.
2. On my brand new iPod, the Genius View has never NOt crashed. I know Genius (and most of Apple's search services) are poor to begin with, but it's a prominent button on the nav. How does it just not work on a brand new device?
3. I'm also guessing the lack of a light sensor on the new iPod was the result of a screwup in the dev cycle...I would've never guessed that its absence would be such a deficiency but when you can't see a single thing on the iPod merely because you stepped from indoors to outdoors...to the point where you have to go back inside to adjust the brightness...that's just infuriating.
I can't remember the last time I've been infuriated by an Apple device...I feel infuriated all the time with my expensive Sony camera and how its video button is right where you can accidentally bump into it when shooting a pic...which prevents you from shooting a photo. The last few Apple devices I've had (two laptops, 2 phones, 2 iPads, countless iPods) have always been satisfactory in terms of polish...not iOS6 nor the new iPod touch

This bugged me a lot after iOS6 update. Also the small things such as when there are App Updates and badge shows up on the App Store icon, clicking it takes me to Featured Apps section - not updates as one would expect. On Android for instance, the update notification takes you directly to a screen allowing you to update as expected.
The thing that continually annoys, and occasionally infuriates me, is the f'ing no-button trackpad on the MBP: a dozen times a day my finger or thumb slips on the thing, just as I'm clicking, and it misses, or hits the wrong link.
Disable the button altogether, and turn on tap-to-click. I used to hate it, but two-finger right-click works well, and the new 3-fingers-to-drag gesture means I never have issues with dragging, which was the main pain with tap-to-click.
