Exactly; once available they should make it possible to have 1-2GHz cpus
which need no caches (simplifying things enormously and making them even
cheaper) and can run at full speed pretty much all the time. I guess
one might even think of abandoning large register files, since the main
memory would be as fast. Context switching would be hugely faster (even
ARMs take a hundred or more cycles to respond to interrupts and Sparcs
take a couple of weeks) which might enable all sorts of interesting
programming tricks.

Now if only they can work out how to include a cpu on the same chip as
a gig or so of MRAM we can getto some interesting machines...
