Basically for what you want to do, surf/videos....basically anything they are selling laptop/wise will probably handle what you want it to do. I use an old P4 laptop for my sofa surfing and it works good enough for me. I personally like heavier notebooks with large metal hinges as the hinges always seem to break on me, that and I like a larger keyboard.
I personally prefer the Lenovo Thinkpad notebooks over much of what is out there now.
