Sorry, I should have been more clear.
I'm not talking about "brain-damaged" apps which mix int and pointer. I'm talking about a different type of brain-damage -- using an "int" to count, for example, the number of transistors on a chip. This "int" overflows at 2^31 meaning that, regardless of the fact that I can now address 1 TB, I'm going to be hit by a different type of problem before I reach that limit.
This is a different problem from the "make applications 64-bit clean". It is to "upgrade" applications so they use 64-bit ints when necessary.
Re: "uh"; I'm speaking from experience as a user of IC design tools which are (1) memory hungry (4GB-12GB for a single process is not atypical); (2) need high CPU/RAM bandwidth (all of that memory is aggresively used); and (3) show a 60% increase in virtual memory when running in 64-bit mode. I am not attempting to present these as "typical" applications; just that they are important to me ...
I anxiously await Intel's entry into the field with IA32e. The ensuing competition will be great for everyone, both in increasing performance and lowering price.
