I tend to agree with many that these designs tend to provide clutter and generally fragment the overall user experience.
I love animations like deleting notes on iOS or minimising a window on OSX or the wiggling icons to rearrange on iOS, but some of those other effects confuse me. Like page turning in iCal (OSX) is weird when I have the side panel open, I'd prefer innovation with their calendar app like being able to see the weeks between two months. Why do most calendar apps force me to see only 1 month at a time when I have events that straddle between months?
Contacts (OSX), I find much more difficult to use now with it's new look, and is generally visually distracting, if they want to make the app appear like a real address book then the pages should turn and I should be able to have A-Z letters on the side that I can flip to, but it's strange that it's static with the list on the left and a single selected address on the right - which just conflicts with what's it's meant to look like. And on the iPad in Portrait mode the app is a complete waste of space only taking up half the screen.
Other example include, Photo Booth which really doesn't need the red curtain to appear and I agree with the pod casting app, game centre app, find friends app, at least we don't have to look at the TV icon for youtube anymore with iOS6 and the new youtube app
With iPhoto, I don't want to download the iPad version cause of it's tacky look (played with it stores a few times) and most of the features seem gimmicky so I hope the same gimmicks aren't translated to the new iPhoto version on OSX, I want better organisation and a much faster app, and I hope they get rid of the carousal for creating books etc but I doubt they will.
All of these fake things are really putting me off, I feel like they aren't serious about experienced users and treating us like newbies or mums and dads using their first computer.
I hope to see some good software innovation with the next iTunes and their new iLife series in the future, but I'm not liking where they are heading generally with software design...
