Just speculating, but if anyone has the financial muscle to do it, it would have to be this company. Right now, I feel Microsoft is starting to feel more than a little threatened by Apple, and the open source movement in general. I see several possible outcomes in the near future. 1. Microsoft kills Office for Mac. Microsofts way of discouraging people not to purchase a Mac. Probably not too likely seeing Mac users will probably be able to run Windows Office in a year or so anyway. 2. Microsoft makes Windows machine specific (i.e, won't boot on new Macs). Not sure how feasible this is, probably not hard if the new Macs are going to have a special "hardware key" to boot OS X built into the motherboard. Just do the same thing for Windows except in reverse, making impossible for switchers to run their old software on the new Macs. 3. Microsoft tries to buy Apple. Probably the most likely. I don't think cost will be an issue with this one. (We're talking about Microsoft here.) As for antitrust legislation, remember the DOJ case against Microsoft? I wouldn't be surprised to see some sort of takeover bid from Microsoft sometime in the near future.
