After using it for about one year, I have following observations:
- decent battery life
- good keyboard
- decent sound from built-in speakers
- hard to open to expand RAM
- poor SD card connector, got broken very quickly
- at some fan speeds, it produces high frequency tone. It seems like fan grill is vibrating. Placing an adhesive tape to parts of grill helped.
- does not remain closed. It slightly opens by itself in a bag, which is dangerous, as some object can get between keyboard and display.
- WiFi sensitivity and range is poor, compared to cheap plastic devices. Antenna is most probably in the base, not in the lid. The issue is worse if power adapter is connected to the left side of the computer, a bit better if connected to the right side.
- BIOS has bugs. E.g. setting of fan speed does not work as described. Cannot correctly detect resolution of a big external screens (5120x1440). Big screen works, but requires manual adjustments of available resolutions.
- bundled USB mini-port replicator (HDMI, USB-A) started to fail after about half an year of daily use.
