compare UX and conceptual models

[cfm]

We should start and maintain a UX and conceptual comparison of the SecureDrop Workstation versus a stock Qubes installation versus a non-Qubes system. For example:

	Non-Qubes OS	SecureDrop Workstation	Stock Qubes OS
Once connected, a USB device is...	immediately available	immediately available to a quarantine VM (sd-devices)	not available until manually connected to a VM

This column layout both assumes and suggests that the Workstation's conceptual model is mostly intermediate between the non-Qubes model and the stock-Qubes model. Right now, this is a hypothesis; it may or may not turn out to be a principle we codify and follow affirmatively. An immediate counterexample:

	Non-Qubes OS	SecureDrop Workstation	Stock Qubes OS
Copied text can be pasted...	anywhere	anywhere, with an extra modal copy-paste operation, except to and from VMs tagged sd-workstation	anywhere, with an extra modal copy-paste operation

Worth starting and adding to, probably opportunistically.
