My dad has a 3GS, an I have my N810. The 3GS battery DIES IN HALF A DAY. WITHOUT USING IT! And I had to jail break it to enable tethering (which he wanted for work), and of course my dad broke it once i went to back to college. And there really are not that many useful apps i could find, just silly ones. Half the time a webpage would have accomplished the same thing (facebook, yelp!, etc..). Lack of multtasking is annoying with GPS, which has to relock every time (backgrounder fixed that). Games I did not mess with that much, as it is my dad's phone.

I just like how SIP and google chat work in the background, and Tear is such an awesome browser, etc. If it was faster, I really would not care about the other stuff. It looks like the n900 is faster, but I don't know for sure.
