So, you like proprietary hardware that you have to pay more for, with less options than lets say, Linux. Yes, Linux is the basis of the whole Macintosh OSX version whatever, but with it, once configured you can use any bit of hardware that'll fit. Sorry about the pro-Linux rant, but yes, I liked apple back when they used vastly superior components (good ol' SCUSI, how I miss thee.)
Edit: Sorry about being wrong about what Macintosh OSX is based on. I should of fact-checked that before posting, but I was tired.
