SMT is considerably cheaper in higher volumes as well. The parts
themselves tend to be cheaper, and the final assembly is much, much
cheap. A robot places all the parts on top of tiny little bits of
solder paste and it goes into an oven, 15 minutes later, presto!
finished board. Contrast that with spending an hour of human time
(+cost of feeding/clothing human, etc) and it's not hard to see why
modern electronics use surface mount components.

Actually, I disagree. At the current pace of technology, many years
from now I may find it difficult to find through hole components to
replace certain dead ones on my boards. Quick, who has easy access to a
68000? Or a core memory winding? Or any sort of vacuum tube?
I agree, soldering a gnats ass to a pad is kinda annoying, but not
impossible. You need the right tools, and they're kind of expensive
right now. You don't know soldering until you've soldered SMT! Where's
you sense of adventure! ^_^
That being said, there's still lots to solder on MOTM kits that can't
be done by machine. I personally enjoy soldering but for me the reason
I buy MOTM modules was to make music, and I find the current turn
around times to be rather limiting. It's also hard to convince newbies
to pony up for a system when it will take over a month for it to
arrive, unassembled. That's a really hard sell, and limits the MOTM's
appeal to the truly hard core (of pocket book, patience, or technical
ability.) How long can Paul keep going appealing to such a limited
group? I don't know.
I hope forever, the MOTM rules.
