Notebook/Laptop are the same.
Netbook is a low powered, low cost smaller computer that does email, web surfing, multi-media and the like OK.
It will run MS Office programs... just slowly and doesn't do multi-tasking well
So a netbook in not a good choice if multi-tasking on the laptop/notebook/netbook is your goal. If one of those tasks is the TV? Then it's a possiblity.
You settled on a budget yet?
