The Lenovo ThinkBook Plus Gen 4 is the most unusual laptop I’ve ever reviewed. Not only does it have a color E Ink display on its lid, but it also features a hinge that lets you swivel the screen 180°. Note that isn’t 360°, which is a shame – I kept trying to twist it in the wrong direction.
So, let’s address the obvious question: why? According to Lenovo, it offers four modes: laptop, tablet, e-paper and typewriting. It also ships with a stylus – although sadly there’s nowhere for it to be stowed – so you can write, annotate and draw on it. I find the Apple Pencil more enjoyable to write with thanks to its greater heft and girth, and while Lenovo’s stylus is precise it’s still no match for a real pen and paper.
The color E Ink display is meant to make reading books and taking notes feel similar to performing the same acts on real paper. It can show anything the OLED panel can, so you aren’t reduced to viewing content made specifically for e-readers. While a novel feature, I wouldn’t recommend it due to the E Ink panel’s low 12Hz refresh rate. Scrolling web pages or documents is choppy, and a ghosting effect (when traces of a previous image remain on screen) adds to the annoyance.
Colors on the E Ink panel also look washed out at best, hitting 0.4% (that is not a typo!) of the DCI-P3 color gamut. Still, it’s better to have some color than none at all.
If all you’re doing is reading or using it as a typewriter, then the E Ink display still has its advantages. For a start, it’s easier on the eyes, but it also cuts down on distractions. Switch on the Lenovo Reader mode and you can devour ebooks, while you can use Lenovo Notebook to scribble notes. If the performance is too sluggish, you can also use Reader and Notebook with the OLED display.
This 13.3in touchscreen panel is as vibrant as you would expect, covering 100% of the DCI-P3 gamut with an average Delta E of 0.21. It’s bright, too, hitting 360cd/m2 in our SDR tests and 480cd/m2 with HDR content.
You can happily watch films on the ThinkBook Plus without headphones, thanks to clear audio and plenty of volume without distortion. Music lovers won’t appreciate the lack of bass on offer, however.
Bearing in mind that Lenovo is pitching the ThinkBook Plus as a typewriter, it’s a shame that it isn’t part of the ThinkPad range with its deep key travel. Still, I found the keys snappy and responsive, and even though this is a compact laptop it never felt cramped when typing (and I have big hands). The trackpad’s small footprint proved more challenging, not always registering my gestures.
While I say compact, I don’t say light. At 1.4kg, this is substantially heavier than the streamlined 13in laptops we see elsewhere, with many now ducking under 1kg. What’s more, they’ll offer far better battery life than the Plus, which gave up after 6hrs 50mins of our web-surfing rundown test. That’s poor.
Finally we come to speed, which is in line with expectations for a laptop with a Core i7-1355U. It’s extremely fast for day-to-day operations, but those who use heavyweight apps or want to play AAA games should look elsewhere. Only one configuration is on sale, with 16GB of RAM and a 512GB SSD, which also restricts usage, but not as much as the fact that Lenovo UK hasn’t announced a release date or price yet.
So, should you rush over to the US and spend $3,039 on this machine? For the vast majority of people, the answer to that is a straightforward no. That’s a shame, as I really wanted to love the Lenovo ThinkBook Plus Gen 4. After all, it’s not every day you come across a 2-in-1 with a built-in color E Ink display and twistable hinge. As foldable phones have shown, having a device that serves multiple functions is advantageous. But while the idea behind this ThinkBook Plus sounds great on paper, it doesn’t live up to the promise — especially for a device at this price.
