My point was at some point maximising screen size is less important than other usability factors. For phone definitely I do not want screen near the edge because fingers are there. For laptop, true, it's less of an issue. Although while opening my macbook my finger is about 1mm from touching the screen. And the other comment about wasting screen space is funny. Yeah we need 1mm of extra phone screen space when 60% of most webpages are covered with ads (separate problem but still amusing in combination).
