Something Microsoft would love, love, love to change about themselves. http://en.wikipedia.org/wiki/Microsoft_Surface
Trying to run OS X on non-Apple hardware makes the old days of "cumbersome" Linux-systems look like kindergarten-stuff.
I'd hardly say it just runs.
Their recommended builds are excellent, even if you were only to use them for Windows.
The best I had was a system which booted (incredibly slowly) and for which I could never get wifi working.
YMMV, but you have been warned. Even with good documentation, there is absolutely no guarantee you'll get anywhere at all.
It's literally build the computer, put the required software on USB drive(Unibeast). Boot computer, format drive, install OSX. Run Multibeast. Voila. Keep usb drive for when you update.
Not true at all. Maybe if you're using old or unsupported hardware.
At most you'll need to set your BIOS to Optimized Defaults.
You mean EFI? Because Macs don't have any special hardware inside, and especially not any "authentic Mac" chips.
The idea that they would charge for these smaller OSX updates is bizarre, and the price point has been in the "we need this for accounting" range in the past.
