I disagree. The highly specialized monitoring equipment and dual high gains antennas and the plethora of other bits and pieces are NOT required to run a "a meeting" or a "netflix stream". A phone with a sim card usually suffice. All this frivolous spending points out that this is a hobby. Nothing wrong with having hobbies, of course, but the spending is not compatible with the definition of minimalism.

A minimalist online meeting is an IRC connection over 3G.
