Firstly, if so many men are doing it there must be something very important in the laptop that warrants our attention. Therefore women should recognize the importance of us having to pay attention to non-trivial matters of the laptop. Secondly, the opportunity cost of being on the laptop is negligible. There is no guarantee that we won't get yelled at while doing the thing we devote our attention to after we close the laptop. Thirdly, I don't think men are reading what they are browsing. I am assuming net surfing is like TV channel surfing. You do it for pretense but are actually lost in some parallel world. Teenagers call it 'chillin out'.
Lastly, that empty smile - thats the light indicator telling you that the 'chillin out' process is still cooking.
