Neat design ; Gorgeous OLED display ; Bumpin’ speakers ; Decent performance

Expensive ; E-ink display is slow

The Lenovo ThinkBook Plus G4 is a 2-in-1 laptop that doubles up on screens with an e-ink display, and it would be great if it weren’t for sluggish performance for half of the laptop.

An innovative, if functionally niche, rotating hinge makes it a truly transforming laptop. ; 2.8K OLED touchscreen offers excellent color accuracy. ; Sturdy metal chassis and a quality keyboard as usual.

E-Ink display suffers from severe ghosting issues and limited usability. ; Priced over $3,000 with regular availability issues. ; Restricted connectivity with only two USB-C ports. ; Single configuration for purchase with no customization.

The ThinkBook Plus Gen 4 feels like an example of 'just because you can, doesn't mean you should' as this CES experiment fails to prove genuinely tempting versus the strong competition from Lenovo itself and rival manufacturers. Most of its internals...

Though I can’t recommend this remarkable 2-in-1 to most people, it’s still an intriguing product that could pave the way for similar (and less expensive) devices in the future.
