I'd seen some talk about implementing WINE on Macs, but Cringely takes the concept farther than I had considered.
Apple wants to win customers who are currently using Windows, so this idea makes a lot of sense. It could be cheaper than getting a Vista PC, and work better too.
HAL - check out "VT" and "hypervisor".
Just to clarify, I understand VT is not the same as provding Microsoft programming interfaces, which would be a nightmare. The concept is, and has been, "integerated realtime duplicity", which Cringely is just now figuring out, but virutalization is how this will be achieved, and has been decided for some time, IMO.
