Last I checked, the life of a BMW and a Toyota is much longer than the less than 2 years that each NIT has enjoyed in the name of "support"

My last BMW lasted 8 years, and in high school to college, my Toyota lasted 9.

Regardless, these are disposable items, especially where firmware updates are basicaly stopped the moment a newer version/iteration of said product comes out. This comparison to paying more for a telephone or NIT in the name of "better quality" but yet it lacks continued support and/or seems already dated from the moment you purchase it is the wrong analogy.

Paying a premium for something that does not get regular support in the way of the rest of the Nokia products is a foolish endeavor no matter how you split it.

And these numbers being tossed around... which models represent this growth?

I still stand by my notion that the mindshare for Nokia is lessening. We've already seen it happen to Motorola. And Apple/RIM has nothing to do with that; they're just competition.
