Apple is a hardware company. Their profit is in hardware. They sell Macs, iPods, iPhones, peripherals, accessories, Mighty Mouses, whatever. That’s their bread and butter, and it’s how they stay in business. OS X is a beautiful, sleek operating system that is designed to sell Macs. They are made for each other, quite literally.
Microsoft is a software company. Their profit is in software. They sell Windows, Office, SQL Server, and other software solutions. That’s their bread and butter, and it’s how they stay in business. Windows does not favor any specific PC maker’s platform (intentionally) and MS is always open to squeezing Windows on anything it will fit on, regardless of who makes it.
Microsoft has no problem with people running Windows on a Mac, since more Windows licenses = more $$$. Apple has problems with people running OS X on anything BUT a Mac, since less Macs sold = less $$$.”—S.SubZero, explaining, yet once again, why Apple cannot be compared to Microsoft.
