The HW is intended for and can be used for general purpose computing. I think you seem to think that for something to be general purpose it has to be able to run everything. I've never heard that definition before and honestly, if that's the case then there is no general purpose computing HW in existence. The standard definition is that it can run, in a reasonable way, most consumer/productivity workloads. It's not about saying "This HW doesn't run Linux" or "It doesn't run Adobe Premiere 12.2". I think you simply want to run other OSes on a device. That's a fine thing to want, but I think you're conflating that desire with other concepts.
