<P> Reviewing the iPhone 4 in 2010, writer Joshua Topolsky commented: </P> <P> "to our eyes, there has never been a more detailed, clear, or viewable screen on any mobile device . Not only are the colors and blacks deep and rich, but you simply cannot see pixels on the screen . Okay, if you take some macro camera shots or get right up in there you can make them out (but) webpages that would be line after line of pixelated content when zoomed out on a 3GS are completely readable on the iPhone 4, though the text is beyond microscopic ." </P> <P> Former Microsoft employee Bill Hill, an expert on font rendering, offered similar comments: </P> <P> That much resolution is stunning . To see it on a mainstream device like the iPad--rather than a $13,000 exotic monitor--is truly amazing, and something I've been waiting more than a decade to see . It will set a bar for future resolution that every other manufacturer of devices and PCs will have to jump . </P>
