If the app stops running, that's *fake* multi-tasking, and doesn't
match my experience; I can't remember the details, but I tested it on
a Nexus One, and the item I was looking at was gone, I had to scroll
again.

Also, I cannot go to last.fm on the browser, play some music, and do
other stuff at the same time, can I?

Anyway, what you do in Android is your problem. The point is that in
Linux we need good PM *with* multi-tasking (not really an argument
against opportunistic suspend, I think, but a clarification from Ted's
comment)
