Equating ubuntu with a mac is somewhat disingenuous on your part.
I don't know about you but I generally don't watch movies when I'm working. Should I feel the need to however - horror of horrors! I can do it in windows without switching OS!
The OP specifically mentioned that he was very keen to avoid POS laptops that will be grinding and juddering after 3 years. 3 years is fairly long lifespan even for a desktop, let alone a lappy. I don't see anything but a mac running well after that length of time tbh.
