It's a lesser, older camera, period. The D80 is closer to the
Canon 30D except that it's higher in resolution. And I am sure,
BTW, that the Canon 30D is soon to be replaced by a 10 MP 40D by
the time PMA rolls around.
Also, I think you really ought to wait for the K10D to actually
prove to be as wonderful as Pentax claims it to be, before
anointing it with your TWO top slots.
Whether or not you think the Pentax K10D is better than the Nikon
D80, or vice versa is obviously a matter of subjective opinion, as
they are pretty clearly very close to each other in ability and
features, with The Pentax having the edge of in-body IS, which may
or may not be a big deal, depending on the needs of the particular
user, and the Nikon D80 pretty clearly having the edge of a vast
choice of modern system accessories behind it which dwarfs that of
the Pentax, not the least of which is an upgrade path to
pro-caliber gear if you need it (something completely lacking for
every system besides Nikon and Canon).
And FYI, I am NOT a Nikon DSLR user, just an objective observer
(who happens to be an Olympus user). Were I deciding on an entry
point TODAY, I would certainly be choosing between the Pentax K10D
and the Nikon D80, but I clearly don't see any vast superiority of
the Pentax relative to the Nikon, which happens to be available
sooner than the Pentax, quite possibly explaining Pentax's need to
undercut the Nikon D80 on price.
I might also point out that NEITHER the Nikon nor Pentax 18-55mm
kit lens (nor the Canon's for that matter) is, frankly, worthy of
serious use. Nikon, however, offers quite a few more interesting
reasonably priced choices (such as the 18-70 and 18-135, both of
which are clearly better).
