I think they are very new and the packaging is not hobbyist-friendly...
It takes Microchip about 3-4 years to get PIC18F and dsPIC to get going.
So I think PIC24 will need some time to get started.
At its current price, I do think PIC24 is more competitive than comparable
PIC18F so maybe it will take less time for PIC24 to take off. However we
should not forget the low cost ARMs and other 16-bit MCUs.

I ordered (and received) the Explorer 16 Development Board from
Microchip. It comes with a 24F chip and a 33F chip (both are PIMs). I
do not see any particular problem programming it, since the instruction
set is pretty much the same as the dsPIC instruction set, with some
slight differences. But, as Xiaofan says, going from that to a DIP is
going to take awhile. If it were me, and I wanted to get something
going right away, I'd just go with the 30F family. You just ignore the
DSP stuff, and basically you have the 24F family (not quite, of course,
but close -- look at the 30F-to-24F migration material for the
differences). So the code could be developed with the 30F and then
later transported very easily to the 24F chip when it becomes available.

Right. And speakig about that, have anyone heard anything
about "entry-level" PIC24's in the same 28/40 pin DIP's
as the PIC33's ?
I think that would help a lot to get them "flying"...
PIC24 should not have nearly the development lag from Microchip that the
PIC18 and dsPIC did. This is because the PIC24 is really nothing more than a
stripped down dsPIC.
