I am going to get getting a laptop in a few months...how does that whole wireless thing work?? like how can people be in parks and stuff and have internet? I know in the house you have a router..or something like that?? any help would be great..also,any recommendations on laptops that are not TO pricey,but dependable.I will be taking it to Germany with me,I want to be able to download the pics I am taking and send them over to my hubby.
