Handheld PCs
The handheld PC form factor has been a concept I've enamoured ever since the launch of Nintendo Switch. Handheld PCs bypass the need for both dedicated home or laptop workstations by housing core content and peripherals on the handheld itself (accessible at all times), and hosting extraneous content at home. This way, you can carry the important parts of your desktop setup wherever you go, without a need to find solutions and waste storage space by synchronising content between two different devices. Less room for error, less labor, more usage!
Even though it was the best intermediary at the time - bridging the gap between tablet and laptop, I somehow have no need for my Microsoft Surface Laptop Studio anymore. That's something I never thought I'd say when Microsoft introduced the most seamless tablet/laptop PC yet.
