Bought the Amazon edition on a small sale. Android 8.0 seems to be pretty snappy, though admittedly I don't have a lot to compare it to. Fingerprint reader has been fine so far and the camera seems to respond pretty well. I'm assuming that's the Motorola camera app, but can't really say for sure. Had one small system update after powering on and of course, the app updates, but system space used was something like 11GB so that's a small improvement over the initial reports.
Only gripe so far is that setting up a second user won't let that second user access the SD card. I'd like to have that set up so pictures and such go on the larger card instead of on the device. I don't necessarily plan to keep it that way, but it would be nice to have.
