where did you come up with the internet?????and web browsing????
Thats called personal experience, no web browser is going to use 4GB of DDR3 RAM, that wouldn't be a issue with that. Gaming on the other hand is different.
I am not saying that he shouldn't get 2 more gigs of RAM, I am just saying there should be no difference with 2 or 4 gigs of RAM when it comes to web browsing and everyday tasks.
