My hp Pavilon dx9000 fits what your dad wants, and it's a good buy. I did have a problem with the computer freezing, but it was solved by using a USB mouse instead of the touchpad. I also had a power surge problem which fried the fuse in the motherboard, but hp fixed it for free even though my warranty had expired. I'm not sure if there are any later versions since I don't keep up with computers anymore, but that was my situation with my laptop.
