My father won't buy me a macbook or imac in a cuople of years. I have a Compaq Pressario V4000 and want to buy a mac mini. Can i use the laptop as a monitor and keyboard, the mac mini, and still use XP and Leopard? (When using it without the mac mini, I want XP, and when using it with the mac mini i want a normal mac mini with my 120GB, the NVIDIA graphics like if i use other monitor)
