Marco Arment has written a great piece on the Retina MacBook Pro. Here's one part, though, I had to comment on for the benefit of readers everywhere:
My only regret about the Retina Display is that I can’t buy a standalone one for my desk, and this one’s not big enough to just prop up the laptop on a stand and use it as the only monitor in a desktop setup.
Now, I usually agree with Marco when we discuss technology, but in this case I couldn't disagree more. I'll go a step further and say that for most people, the Retina MacBook Pro will be plenty big enough when put on a stand and used as a primary screen all day long.
In fact, that's exactly how I've been using it for almost a month now, and for the first time in my life, I am actually using a laptop's screen --or heck, any monitor in recent years-- as my primary screen without the slightest discomfort, eyestrain, or problems.
Would a bigger screen mean I'd command-tab a bit less, have more room for palettes, that kind of thing? Of course it would. But the clarity and sheer joy of staring at this screen, especially for people with four eyes like me, is way more than worth it.
It really is a miracle screen.
