the plot thickens. Interesting. So, the
existing macbook pros shipping now don't have the problem, you
think? Sounds like the mac OS might be the benefit in this
case.

Here is the most succinct post I can find on the subject.
I was a little mixed up - it's not that 32-bit OS's can't see all 4GB, but at
least with PC architecture, about a gig of that 4 gigs will be assigned to
system level devices (video card, PCI bus, etc), leaving you with less than
4GB. In addition, 32-bit apps can't access more than 2GB each without
PAE (which is a bad idea for an audio machine).

On
a Macbook Pro, this RAM-shortage might not be a problem - WITH THE NEW Santa
Rosa platform. It is definitely a well-documented problem with all other
Mac/Intel platforms. The new "36-bit" chip allows access to 4GB, and
presumably (this is where I'm not positive) OSX can really use it all because
it doesn't do what Windoze does (steal some of it). In addition, 32-bit
Mac apps can still only access 2GB each.
Hope that
helps.
