Another Apple event has come and gone, and there's still no MacBook Air with a Retina display. I won't blame you if you're frustrated -- now that there's a 5K iMac, the Air is Cupertino's last screen-packing computer to ship without an extreme-resolution display. For that matter, competitors haven't had qualms about releasing their own ultraportable laptops with extra-crisp visuals. So, what gives? Is Apple holding back? The company may not be offering answers, but it's most likely that the technology needed to make a Retina-equipped Air simply isn't ready for prime time. As much as Apple would like the Air to hop on the high-res bandwagon, it may have to wait until a whole bunch of pieces fall into place. Read on to see what I mean.
