I received samples of P2 and M2. the first impressions are very positive. I checked the launch of the official versions of Ubuntu 18.04 from Fyrefly. Everything starts and works from the SD card. The startup process is very simple, I downloaded the image, unpacked it, wrote it to the SD card, connected it to P2\M2, turned on the power and the system automatically updated the bootloader in eMMC, rebooted and the Ubuntu system automatically started from the SD card (the regular Station system in eMMC is saved and works if there is no SD card).
I really liked the mechanism for connecting SATA devices (SSD\HDD) to P2, it is very simple. I immediately connected a 240GB SSD drive. It was automatically detected and appeared in the system. WiFi antennas on P2 are full-fledged and large, they obviously did not save money here and will ensure proper operation.
