I will grant you most laptops don't run an open source os, but most of the times they are probably running a browser -- and both firefox and chrome are almost open source. For mobiles it is a little different, because iOS locks people to their browser, but at least on Android users would be using Chrome. Heck I am typing this on a chromebook, simply because I realized 80% of what I do is webbrowsing anyway.
