you're gonna have to wait some years for that buddy. retina display is just a marketing term for 960x640 resolution on a 3.5 inch screen.
apportioning 960x640 to 10 inches is impossible with current technology.
THANK YOU!
It's a friggin smoke-and-mirrors marketing term.
I see users on this forum rampantly applying the term to other devices, it's appalling. I even saw someone use it to express a fantasy of a higher resolution MacBook screen...
