Johanna Stern blogs about her first impressions of the new Mac Book:

We don’t need all those other ports, Apple says. We are living in a wireless world now, where we can connect most of our peripherals without cords. Except every morning I plug my Air into a Thunderbolt display, and every afternoon I plug my iPhone into my Air to charge it. Of course, Apple will sell dongles—overpriced, naturally—that allow you to do those things.

There’s also no fingerprint reader, like the iPhone and iPad’s TouchID.

But when I opened up the lid and gazed at the 2304×1440-pixel Retina 12-inch screen, those issues faded away. The edge-to-edge display is crisp and bright—a huge improvement over the current MacBook Air.

I’m highly anticipating actual reviews of this thing. My gut feeling¹, that undoubtably has been wrong a lot before, tells me that in five years laptops like this one will be the new default, much like the MacBook Air/Ultrabook is the default right now. But just lite the original Air on its first launch, this will not in itself be a compelling product to that many people. It is certainly not the right laptop for my needs.
