LOLWUT? you do know that just because the screen resolution increases it doesn't mean the underlying DATA resolution changes at all right?
That being said, I like that Apple is pushing us to higher screen resolutions. I just hope it trickles down/up to desktop/laptop displays having higher ppi as well.
Also, did THEY claim that it would have more pixels than any device? Because that is just ludicrous. (see IBM 22" T220 displays) Any MOBILE device is probably true right now. (although the Asus Transformer Infinity is just a smidge below that)
