Unfortunately I just learned that Apple is has already discontinued the 17" MBP and Apple marketing has this quote:
But if you’re looking for a reason why Apple offed the 17-inch now, you need go no further than the 15-inch Retina display MacBook Pro. Not only does it offer the most cutting edge technology of any Apple laptop to date, but its 2880-by-1800 pixel display outstrips the 17-inch’s 1920-by-1200 resolution with room to spare
The numbers quotes are a larger pixel count than the 17 inch model allowed even with the hi-res display but I haven't played with or seen a MB retina display in person yet. Can I set the pixels to "actual size" so that when I do web design I can have a browser set to normal scale but see a LOT of the web page - or for that matter, any app?
I like the idea of a Retina display but if I can't set the display to show the pixels at "actual size" it seems like I am in fact still losing screen real estate even though there are "more pixels" if that makes sense.
