n8 doesn't do well at all.
I benchmarked my n900, and well... it is quick to take photos and thats about it.

My n900 can.
17 seconds to e-mail (when my n900 is running smooth)
46 seconds to find a destination
5 seconds to take a photo and auto focus.

comment: Nokia it looks like to portrait keyboard is a good idea after all ! and the n900 PIM is still at the bottom of the pile.
