I would compare "new VS new" and "Used VS used"
If you are into used computers then get a used PC at your budget.
You will get something better then that little crApple macbook.
If you like the Mac osX then instead of going Windows you can install Ubuntu or mint on the PC.
It it very similar to mac if you use the gnome interface. (not gnome shell)
Plz tell me if you don't understand what i am talking about.
Here is an image of Linux Mint
