Basically everything is modular. It's a huge design boon to be able to split things up and it comes naturally with reparability and to some extent upgradability

Basically everything is modular. It's a huge design boon to be able to split things up and it comes naturally with reparability and to some extent upgradability. About the only thing I would be careful about replacing (but we'll still be offering) is the optical assembly, as dust will be pretty annoying if it gets in. We're planning a clean room just to handle the dust-sensitive parts of our equipment (image sensors, displays/optics, etc)
