We completely agree on the first two points. You need an adapter to connect a Chromebox to non-DVI/Displayport monitor, and the Chromebox audio port needs a ground loop isolator to make a useable connection to external speakers.
Re: shared WiFi on Chromeboxes / Chromebooks... My experience is that changing or configuring shared WiFi settings is not simple. For example, except for the first time a WiFi connection is configured by a user, I see no user-facing way to enable "share this network with other users". The very FIRST time a connection is made that option displays. I see no user-facing way to change or enable the setting later. For busy IT managers, I recommend using an Ethernet connection, if at all possible. I expect that managing WiFi settings will improve as Chrome OS evolves.
