I agree that the N900 won't be for the average Joe. It's has a solid foundation for being a killer device for the average Joe. Right now it doesn't have a pretty structure (applications) on top of the foundation that people think they need nor the familiarity for people to "risk" buying. All of that takes time and that's probably why the Nokia people say the N900 is step 4 of 5.

If I was a betting man, the next generation N900 (step 5 of 5) won't be much different from the present N900 from a technology standpoint - but will have a lot of flash, glitz, applications (good or not, but enough to fill up pages of the OVI store) & a large marketing budget to get the average Joe to buy.
