ICE 4000

- Full speed emulation
- Low voltage emulation down to 1.8 volts (or device limit)

And I've done 3.3V emulation with ICE 2000 myself.  So his statement
is not correct.

I don't know why the Real ICE is being touted as the next big thing;
it's just a souped-up ICD2.  It has all of the annoying limitations of
the ICD2 like severely limited number of breakpoints and instruction
skidding.  The new trace feature is a kludge that depends on a
particluar compiler and requires MPLAB to modify and recompile your
code.  And I don't know what happens if you forget to remove all of
the trace/log macros inserted by MPLAB before you do a production
build of your code.
