As others-have Said, pity hangouts That Does not use h264 when available, and pity That Does not Clearly certify Logitech webcam as this Linux-compatible Somehow without people having the need to look all over the net afraid of buying a brick.
A Linux certification / support is an added value, I have many friends and relative equipped with Linux installations (intel NUCs and small form laptop) for ubuntu / kodi / skype combos And They love them.
So 1 less star for a very nice camera (very good picture quality Compared to say hd cams of smart-tvs) Because The Linux support is not provided / certified.
