I get that you think the N82 is the greatest thing ever made, apparently largely because it has a Xenon flash (since that is the only thing that really makes it stand out from a number of other recent Nokia N series phones).
My point is only, and I will try to make this a simple as I can for you, that the Xenon flash is not everything. It's one factor amongst many. In the long run, it is not the most important, other improvements like the sensor and the lens will matter more. Whether or not the N86 will be an improvement remains to be seen, I agree on that point. But flashes are just one factor and they're generally considered not the best way to deal with low light situations. Flashes are not the hallmark of good photography. They're the hallmark of bad snap-shot style technology and bad photography. Camera phones can do better with improvements in sensors and lenses. This is not unrealisitic. But why should the cell phone manufacturers bother, if they can fool conumers with cheaper easier solutions like flashes and ever more megapixels?
(And also, if the N86 turns out to take better photos in all situations except those few where a flash is handy, I would choose the N86 for better pictures in 90% of the situations, as you put it, than cling to the N82 because it remains slightly more useful in extremely low light situations--in which the N82 will produce a slightly better ugly flash based photo, than the N86's version of an ugly flash based photo.)
