I never could see the point to those. It's much
easier just build up
your device using the bare chip.
The AVR chip is easy enough to build into other devices, but the big
advantage of the Arduino boards is that they have the USB-serial chip on
as well, which is a much fiddlier SSOP-28 package. Other than that it's
pretty much just a breakout board for all the pins; if your application
doesn't require many external components (e.g. the remote control
receiver I've got sitting in front of me at the moment) then building it
on top of an Arduino directly makes sense.
I've built a few more complex devices that use an ATmega8 with the
Arduino bootloader (so you can use the Arduino toolchains to program
it), running jumper wires across from an AVR-less Arduino board to
provide a power supply and appropriately level-shifted serial port
during development. I've also used the Arduino board as a cheap
USB-to-TTL-serial converter for retrocomputing purposes...
