I just got back into playing with PIC's about a month or so ago, after
being out of it for several years. When I quit, I was using the
18F452. When I started back, I decided (based upon the advice of this
group) to go with the ds3013. My reaction so far has been that for the
"average" hobbyist (different people probably have different ideas on
what "average" means) it might be a little bit too cutting-edge
(bleeding edge?). I like the 3013, and intend to stick with it, but if
I had a definite project in mind to accomplish and saw the PIC as only a
means to an end (rather than an end in itself) then I would use one of
the 452's that are in the drawer. The reason is strictly because there
just are not that many tools available (yet) that support the ds3013,
and if you run into difficulties then getting assistance is easier with
one of the older chips. I like the Wisp628 a lot better than I like the
ICD2, for one thing. There are good programming examples available for
the older chips that don't exist (yet) for the 3013.
That said, however, I will say that so far I am really impressed with
the architecture of the 3013 (and presumably the whole 30F family, but I
haven't looked at the rest of them). The instruction set is impressive
-- lots of creativity went into the design. I haven't gotten to the
point of really looking closely at the DSP instructions, but the initial
reaction was just that they wanted to make it easy to do some involved
mathematical calculations. Doesn't help me, doesn't hurt me.

I agree with Olin on that. The only reason that I looked at C30 was
because I could try it free for 60 days, and figured I should see what
it had to offer. You already know my reaction to that. :-) But the
material that Microchip makes available at no cost is great, other than
for the fact that it only runs under Windows. If it ran under Linux
also then it would be nice.
