Microsoft unveiled some intriguing changes to its Surface Hub 2 earlier this week. The giant 50-inch display will now ship in two versions, and the Surface Hub 2S model that launches next year will include a modular “processor cartridge” that will let owners upgrade to the Surface Hub 2X in 2020. The cartridge slots into the rear of the Surface Hub 2 and upgrades its internal components, including the processor, motherboard, and RAM. It’s simply the guts of the entire PC in a puck-like size.

These cartridges will be used to upgrade the Surface Hub 2 over time, and even service the devices if parts fail. Essentially, the Surface Hub 2 is a now giant display with a removable PC attached to it. This sounds like a great path forward for Microsoft’s other all-in-one pc, the Surface Studio.
