For a dell or gateway.....you really pay for what you get....
For an apple, you OVERpay for what you really get......mostly because of the hardware components........
I always try to get a laptop without an os, because many vendors put junk on the os, and rig the registry....so you cant uninstall it....you have to remove it by force......
Since mac os is not x86 compiled.....just get OSX and slipstream some scripts and homebrew patches, and you can actually run it on a computer you want to run it.....not the one your forced to...
