This doesn't sound right. The storage changes came around honeycomb 3.2 or something like that. External + Internal storage works fine on other devices running ICS (xoom, for example)
Yea sounds like a pretty dumb excuse. That's implying that every phone with ICS in the future won't have an SD slot.
They're making it a point with ICS (and beyond) applications to have the menu button either displayed in the app as the 3 dots on the action bar or somewhere else. I'm fine with the idea because it's silly when you have to guess whether or not the app/screen you're in has extra options, but they should've went with on-screen softkeys to make it less ugly.
Why that youtube app has the menu button displayed, I have no idea.
I guess I could live with that. But there are times, such as on the homescreen, where the option button comes in handy. Or in the middle of a full screen game or something.
