Better appearance (in my opinion), larger speaker (1.6″ vs. 1.5″), able to support stereo pairing and connect to the Echo sub, more power (uses a AC adapter that outputs up to 15 watt via a connected cable with a barrel connector, vs. the 2nd’s gen’s AC adapter that outputs 9 watts via a USB connection, connected to that unit via a USB to micro USB cable), the white (Sandstone) unit actually comes with a white AC adapter and cable, and it supports Spanish and Italian (which still don’t show up on my 2nd gen Dots)
