Lenovo has unveiled the ThinkBook Modular AI PC, a concept of a modular laptop that features a detachable dual screen and keyboard, and swappable ports. While still in development, it feels like Lenovo is close to a completed product. The laptop's second display can be snapped off to either take the keyboard or stand propped up next to the laptop as a standalone portable monitor. The swappability of these swappables indicates a level of modularity that Lenovo hasn't seen on its mainstream laptop line. However, the lack of plastic modular ports on this ThinkBook's I/O is more limited, with only limited versions available so far. The concept is seen as a significant step towards a more flexible device concept.
