It does not seem totally logical to me that one checks for updates by selecting 'Settings' on the touch screen. The original Almond was better in this respect (with a 'Software Update' app); but all models since then (including the A1A) seem to use a 'Settings' app.
The Web UI is a little less confusing with a 'Firmware' button (2015, A1A) or 'Software' button (original, +, 3); but even here it would be nice to be consistent.
