Mac stability comes from the fact the OS is only tailored for macs, compared to a PC which is jumbled-up pieces of random hardware stuck together and because of this, the hardware and software combination is far more expensive in comparison to a normal non-Mac computer which Apple do to get a big profit. Developments in Open Source software over recent years have made a big impact to the limited programme issue, but many Microsoft products aren't accessible. Though now, you can dual-boot in either Windows or OSX, but that is really up to you.
