I would divorce my Wife if I found out she used MySpace.
So you wouldn't divorce her for using Bebo?
The reason the 3gs "outperforms" the N1 is because the N1 has more than twice the pixels of a 3GS. If the N1 had to drive the iphones resolution, it would wipe the floor with the iphones ass, all while supporting user app multitasking.
What many people are forgetting is that the N1 has no GPU, it requires the CPU to do all the rendering, which makes the rendering a little slower.
We are better off comparing it to the Motorola Milestone (Droid in the US) which has a GPU.
