I would second that.  They seem to have decided on their pricing policy
in the old days when a 64-bit chip was a really big deal, and basically
only used for very high-end workstations or for servers.

Now, on the other hand, you'd actually have to go out of your way to
find a 32-bit machine to buy.

I think if we chip away at them they will eventually give up on their
model of 64-bit as being worthy of a cost premium, and start to ship a
Professional (and presumably a trial) that's 64-bit.  But it will
probably take a number of people complaining.

I know I made Duane Rettig wince when I said at ILC that we'd ported our
system to SBCL to get a 64-bit version.

Best,
