Hlorri thanks for the detailed response to my question. I believe the Pre and G1 do have some of these features (MMS, copy and paste, multi-tasking, microUSB, SIM card in the G1 and eventually in the Pre when the GSM version comes out, browsable file system). I'm not sure about some of the other features you mention. And I know people love the Opera browser, but I just can't imagine how web browsing on the N86 could possible be better than on the iPhone, Pre, or G1; to me this is one thing that the large touch screen interface excels at.
That said, your list of features is very interesting and food for thought. Thanks for going to the trouble to respond in so much detail. I do like the TV out and VOIP options. And of course simply the quality of the phone as a phone is important and strangely so often overlooked in phone reviews. I know the iPhone is pretty mediocre in this department. I don't know about the Pre or G1.
I guess if you put the interface aside (which of course is not a trivial matter, I think), in some ways the Nokia N series phones still cram in more different features--in a Swiss Army Knife sort of fashion.
