(Partially moved the contextually relevant parts from old topic...)
I think that video capability should be optional (that's why it didn't bother me when I built my Parallax Propeller based test platform I have that the Parallax Propeller's USB host capability is sort of slow for webcam use...I figured a laptop would do it if it was needed...sort of like you add a compressor and tank for pneumatics if you want them). I think if you can remove features you don't want...and are resource expensive like this...the more variance you can have in what you use that weight savings for elsewhere. Some teams might not want to tackle the challenge of video processing (even though libraries like PyGames are making that easy as Py
)
So I would think flexibility....but not at the expense of reliability or practicality should be a priority of some sort.
