I'm actually on the same page with Mark. To me Android's history mechanism is more of a hassle than a benefit especially if you use view=activity anathema. Personally I found that views inflating is not that slow at all. I didn't measure memory footprint of my applications but Hey, let Android swap some other application out if my app needs more RAM :) At least I won't have to bother with endless activities nightmare. Perhaps I should look into FrameLayout more closely.
