Vanishing keyboard aside, the Yoga Book includes a pretty standard set of components for a budget laptop, with an Intel Atom x5 processor, 64GB of solid-state storage and 4GB of RAM.
The price reflects these lower-end internal components, at $499 in the US for the Android version and $549 for the Windows 10 version.
This is the only laptop I can recall taking to a coffee shop without a case, bag or anything to carry it in.
I just tucked it under my arm like a slim paperback.
But that largely depends on your creation versus consumption patterns, and -- for creators -- what you're actually working on.
The most striking feature of this slim 10.1-inch hybrid (available in both Windows and Android versions) is its keyboard, or at least the space on the clamshell body where the keyboard would normally be.
The result is a fun, highly portable device that instantly appeals to creative professionals -- but one that's not nearly as practical as Lenovo makes it out to be.
That doesn't mean it can't be an option for your secondary or travel computer, instead of a Chromebook, i Pad or other small-screen budget laptop.
They're £449 and £549 in the UK, and AU9 and AU9 in Australia, respectively.
Both versions have the same internal components, but the Android model has a few keyboard/touchpad changes, some Android-centric software tweaks, and comes with a grey lid, versus the black lid in the Windows version.
