Having a retina display while actually losing screen real estate seems a bit counterintuitive...
This. I was hoping they'd up the 13" MBP to 1440x900 as standard and then retina-ify it, and make the 15" MBP 1680x1050 by default and then retina-ify that.
I (personally, before anyone comes for my throat) would prefer retina AND more physical space on screen, or if I had to choose, just more physical space on screen.
I'm not too fussed about retina. Sure it's cool, but it isn't a replacement for more physical work space. I'd rather make the 13" more usable (multi-tasking on the 13" is slow purely because of the amount of time you have to spend flicking between windows/Mission Control/etc.) and have the 15" have the high-res screen without having to BTO.
