A very attractive idea, and good specs to boot. One downside: RAM is limited to the 4 GB on board. That is unfortunate, as 4 GB can be more limiting than anticipated once one gets going, and the SoC (generally a good pick, btw, assuming Qualcomm is more reasonable about documentation with this IoT SoC) is quite brawny and can easily make use of twice that - an 8 GB option for a little bit more money would have been a cherry on top.
Lastly, isn't that more or less the SoC used by the newest Fairphone? Although that comes with more RAM, of course.
