And you paid more for that than a regular PC why?
Its not like you cant get FreeBSD etc for sensibly priced hardware?
Edit.
And despite having a BSD core, Leopard/Snow Leopard are the most insecure OSs on the market today.
It was more in response to the "Fisher Price OS" thing, an OS is only as secure as the user lets it be and, in the real world, OSX vulnerabilities are far fewer and less severe than those in Windows.
I paid more because the hardware is better (Im not just talking about the processor & RAM here, my MBP is, literally, hewn from a solid hunk of aluminium), the OS gets out of your way and lets you do more work, the available apps are far superior in the vast majority of cases, the buying experience is better and, frankly, because I can afford it and a couple of hundred quid is an inconsequential amount over the life of a system to have what is, in my experience, a much better workflow.
Also, prior to buying my MBP, I had one of the polycarbonate MacBooks. I bought it for £820 and sold it over a year later for £700. A lot of the price difference is made up in resale value.
