Thought you would like em, I got my son a set for his laptop at uni. 5.1 was a bit overkill in his case too, and a bargain for £40
I would keep shopping around for a laptop, just decide on the main stuff (memory/screen size/DVD or BluRay etc etc) and then go for the one you like the look of, bit like a car they all do the same thing just some are quicker and nicer to look at
