This is beginning to change.  I think I'm going to try learning.  The
numbers are just to good, 250,000 logic gates that run at 100Mhz all
on an easy to interface PCB with software for $50.

And the best part is you can re-program it up after to build
something.  So you only need to buy one FPGA board.  They get
re-programmed on every power cycle. and (2) not waiting to order
parts, you can try an idea right away.

The Up is easier to use but always you end up with a bunch of other
ICs in the design.  the FPGA should let you do most of hat those ICs
do and whatever the uP can do.

For $50 I'll learn something, even if it is "These things are not as
useful as I thought."

And I agre with you about the CPU cores.   Just use them.  My guess is
that most FPGA  applications have a uP core inside.
