Recently I came across this problem.
I had downloaded some podcasts on the iPhone. At work when I have no
Podcasts to listen to I grab some thru the iTunes app on the phone. Before iOS 5 the podcasts were treated like any other podcast that had come from a iTunes sync. But now those podcasts seem to have made a home on my iPhone and would not be deleted. Listen to or not.

Gestures do solve some ui problems. Just not all of them. If you don't know it there you can't use them. It's not a new flaw it's a old one. If a command is buried in a menu and you don't know about it, you can't use it.
Photoshop is guilty of this. Content aware fill is a great tool. It's not a 100% fix but workable. I recently used it for a clean plate. Got me close and I painted the the rest of it. This tool fills in areas with content from surrounding areas. Sounds cool, huh! It is, but it's in a menu. My dad might use this a lot but I had to show him that it was there. Gestures adds a layer we didn't have before. Going from on the road with my laptop to my office is a change. My MacbookPro is plugged into a external monitor. As a result I no longer have a track pad. And now with the change to more of a iOS interface in Mac OS X a track pad is almost a must.
