What will laptops look like in 3–5 years? Lenovo ThinkBook modular AI PC concept unveiled at MWC 2026

Lenovo is once again playing its favorite game: “here’s what computing might look like in 3–5 years.” This time, the company revealed renders of the ThinkBook Modular AI PC — a modular laptop where the keyboard can be replaced with a second display. For now, it is purely a prototype shown at MWC 2026, but the concept is intriguing enough to raise a real question: do we actually need this?

What the Renders Show

At first glance, it looks like a classic clamshell laptop with slim bezels. The key innovation is in the lower half: instead of the traditional keyboard and touchpad, you can install an additional touchscreen display.

Some versions even show the main display detached and positioned to the side — almost like a tablet connected to a keyboard base.

The idea is simple and not entirely new:

• Want to type? Use a physical keyboard module.
• Want more workspace? Swap it for a second screen for notes, tools, chats, drawing, or multitasking.

All of this is supposed to integrate with AI features — hence the “AI PC” branding — though Lenovo has shared very few details about the software side.

Obvious Advantages

• Flexibility: one device, multiple use cases. Code in the morning, sketch in the afternoon, run dual windows anytime.
• Less hardware on your desk: instead of a laptop + tablet + external monitor, you get a single modular system.
• Creative potential: designers, video editors, and developers who rely on second screens could benefit.

The Downsides and Open Questions

• How secure are the modules? Magnets? Connectors? Rails? If a module detaches accidentally, that could be a serious issue.
• Weight and balance: replacing the keyboard with a screen shifts the center of gravity. The device might become unstable, especially when used on your lap.
• Price: modular systems are almost always more expensive. Replacing a module could cost nearly as much as half a laptop.
• Keyboard ergonomics: a detachable or ultra-thin keyboard may involve compromises in key travel and comfort.
• AI features: it is still unclear what “AI PC” truly means here — just a processor with an NPU, or something more advanced and context-aware?

Lenovo often showcases bold concepts at MWC — from rollable displays to transparent panels. Some ideas quietly disappear, while others eventually reach the market in simplified form. For now, the ThinkBook Modular AI PC looks like an interesting prototype, but the road to a commercial product could be long.

Who Might Benefit Today

• Designers and illustrators who want quick switching between keyboard and tablet modes.
• Programmers and analysts who constantly need a second screen for documentation or terminals.
• Users tired of carrying both a laptop and a tablet and looking for an all-in-one solution.

For most people in 2026, however, a traditional laptop with a good 16:10 display — or an external monitor — will likely remain the more practical choice.

In Brief

Lenovo unveiled the ThinkBook Modular AI PC concept at MWC 2026 — a laptop where the keyboard can be replaced with a second touchscreen. The idea is flexible and compelling but raises major questions about durability, weight, price, and ergonomics. For now, it is just a concept, and it may take years — if ever — to reach mass production. For most users in 2026, a conventional laptop still makes more sense.
