For modular PCs to really make sense, the entire PC industry would have to band together for some sort of standard, or at least a broader platform that lots of vendors can tap into. In theory, PC vendors such as Acer, Lenovo, and HP would offer the base stations, and they’d all work with the same modules from a variety of component makers.
This sort of collaboration would eliminate many of the issues described above, from ecosystem lock-in to transferability of modules between different machines. If such as system became the norm for desktops, you could then be confident about the availability of upgrades five or ten years down the road. Unfortunately, one-off attempts like the Acer Revo Build do little to nudge the industry in that direction.
