A:Answer Nest Point does NOT have any ports; only a power cable; and a switch for on/off of the speaker (allows "Hey Google" function, like commands and music). The Google version has ports, so can act as router or point; no speaker/mic switch. Size is different in contour/shape, esp. height and width differences, if you are fitting into a specific spot. / I upgraded from Google to Google Nest on the router and just one point; it says compatible, which it is, but how to do this-- no instructions. I ended up online chatting with Nest tech support, as I had to reset all the older Google points to recognize the new Nest Router. It was a pain; slow (Google Points can be slow, but eventually work)... and it disrupted every smart item I had connected; trying to fix, it canceled my subscriptions during some factory resets; everything had to be reconnected by app or by touching the device. Partly my fault, but a huge problem was no How To guide or instruction for the scenario of switching from Google to Google Nest. It just says "compatible". Probably easier when first setting up. A problem when there is a Google mesh already set up. The company in the app, FAQ, on box... should remind you how to factory reset the (older) Google points.
