That falls right in there with the "No more assembly code in drivers,
guys" edict. Blech, says I.

Absolutely they are. And they should be!
A hard limit of 4GB of physical memory, and 2GB of user-mode virtual address
space, is really not enough for a lot of memory intensive applications today.
As the emphasis shifts from devs writing tight, efficient, code to code that's
easier and faster to develop (and more secure at the same time), many
applications have gotten larger. Sometimes MUCH larger.
Even on systems that do data acquisition and processing, the ability to use
MUCH larger amounts of physical memory and to manipulate MUCH larger virtual
address spaces makes it simple to do things that are very difficult in smaller
address spaces. Larger address spaces can help reduce paging, which ALWAYS
helps reduce latency (of every kind).
Oh, yeah... and what Tim said, too: "To help Intel sell more PCs and eventually
force people to upgrade to newer Microsoft software."
