Mac gave up...Bill Gates wins
Maybe. Predicting these things is close to impossible.
While dual boot may well be popular with home users, I can't see it being a such a big deal in the IT world. In a work environment, rebooting your Mac just to get email from an Exchange server is not likely to be a big winner.
However following on from the links posted above about virtualization and the ability to run OS X and Windows at the same time, some interesting possibilities present themselves.
An organization or department might be able to run a wholly *nix based infrastructure. Linux/Unix on the servers and big iron and Mac on the desktop. "Must have" Windows desktop software would be supported by virtualization on the Mac.
Why would anybody want to do this ? One reason may be superior security and far less exposure to the risk of malware of various types which is both costly to guard against and potentially very costly in terms of down time. Another might be the 'standardization' of Apple hardware. IT support not having to deal with the myriad combinations of video cards and drivers and whatever, that happens in the PC world.
There are a lot of benefits to virtualization and I think it's destined for widespread adoption. Just one example. If the guest OS (eg Windows) gets clobbered by malware, the guest OS image is just a file that can be recovered from backup very easily. The time consuming procedure of Windows reinstallation is entirely removed.
Some of these things may well add up to a lower cost of ownership that we hear about so frequently.
