I believe 2008 works the same way, though I have not tried it. I seem to remember that upgrading from Linux gives more control and allows, for instance, kernel upgrades without fragging user space.

You could have read that anywhere, as it is truth :) kernel upgrades require a reboot to be applied and are risky if the kernel is (for example) built by an idiot user (such as myself) who misses a block device driver required for boot or something... :P There was an earlier comment about not allowing linking of something that I did not at all understand. I think it is ridiculous to have to flash a device to upgrade the OS when it is fundamentally debian under the hood, but I am also a stupid user and do not understand the subtlety of true linux gurism.

My initial response to the flash requirement was the same ("You've *got*
to be kidding me!") but there's one significant difference in N800 et.
al. that doesn't apply to Debian-based systems in general: extremely
limited storage space. An OS upgrade can require a lot of core packages
to be upgraded simultaneously (glibc, busybox, dpkg, apt, etc.) There's
simply not enough free space on a standard N800 to download everything
and install it all at once. Additionally, Debian upgrades get a huge
amount of testing resources which is probably not available to Nokia.
Combined with a long history of "just re-flash it" style upgrades in the
embedded industry, I can understand why Nokia made the choice it did.
The good news is that OS2008 should support more-or-less automatic
restores of your install packages, and Nokia is working on supporting
"real" Debian style upgrades, possibly for OS2009(?) (but I don't have
the link handy).

That makes sense. It seems like an alternate path would be to change
apt-get a tiny bit and have it download/install packages serially instead
of in parallel (where possible: dependencies permitting). Also, the N810
has more flash space than I have ever had on mobile device. Come to think
of it, the N810 has more flash space than my first debian box had disk (by
a factor of 2.5!).

I look forward to that. Unfortunately, reinstallation of packages is not
by any stretch the only aspect of bringing a system back to the way _you_
(one) likes it. There is a significant amount of data and customization
usually involved as well.
Of course, there is always the point where it is _so_ overly customized
(and broken) that it is easier to start fresh. Always nice to have options
:)
