Today, Lenovo took the wraps off the Yoga Book: A new tablet/laptop hybrid, offered in both Android and Windows 10 flavours, focused squarely on helping users be productive.

Like most tablets made in the last two years or so, the Yoga Book is taking its cues from Microsoft.

Unlike most of those tablets, the Yoga Book seems to be inspired not by the Microsoft Surface, which even Apple has imitated with its iPad Pro — but rather the Microsoft Courier, a hotly-anticipated tablet that was first leaked to the press in 2008, and then killed on Bill Gates’ orders in 2010, before it was even officially announced.

The Courier would have been a dual-screen “booklet” PC. Rather than a keyboard, it sported two 7-inch touchscreens, connected by a hinge. With those two screens, you could use it as kind of a so-called “infinite journal,” sketching or taking notes with a stylus on one side while reading the news or making appointments on the other.

Here’s a video of what the Courier’s interface would have looked like:

Now meet the Lenovo Yoga Book, announced on Wednesday, and shipping in the US by the end of October.

Lenovo The Lenovo Yoga Book.

It’s billed by Lenovo as a super-thin, super-light tablet. You may have noticed already that it doesn’t have a keyboard, in the traditional sense. Instead, it’s a funky kind of touchscreen, called the “Halo keyboard” by Lenovo, that basically tries to recreate the feeling of typing with a regular laptop keyboard without actually being one.

The Halo keyboard also gives the Yoga Book its best, and most Courier-esque feature:

The Halo keyboard pulls double duty as a sketchpad, thanks to its neat wide-open hinge. If you lay down a piece of paper on top of the keyboard, and use the stylus that comes with the Yoga Book in its ballpoint pen mode (seriously, it switches), any notes you take will instantly be digitised and put on the main screen. It does the same thing without paper and with the stylus in its normal mode, but, well, that’s less fun.

Either way, as you can see, the spirit of the Microsoft Courier lives on in the Yoga Book. The second screen isn’t quite the full-on touchscreen promised by the Courier (the Verge reports that Lenovo tried, but the second screen degraded battery life too much), but the core concept of a dedicated sketchpad has clearly endured.

There’s a case to be made that despite the hype, the Courier was little more than a science project that deserved to be killed. But times have changed since 2010, and maybe the moment is right for a stylus-driven tablet after all these years.

The Yoga Book will be available by the end of October, starting at $499 for the Android version and $550 for the Windows 10 model. And while it remains to be seen if Lenovo’s gamble on a more offbeat kind of tablet will pay off, it’s very nice to see a company finally think a little different.
