It gets automatic regular firmware updates to stay insync with Chrome OS, so it should always be patched.
It has a dead simple user interface, though it means many power user features are not there. Though there is a project out there to root the device and do more with it. https://github.com/marcosscriven/galeforce
I feel like those features and probably a few more that I couldn't think of off the top of my head are going to cover 99.99% of all users' needs. I agree there are other devices, especially if you flash your own firmware, that will give you more fine tuned control. I just didn't want to leave anyone with the impression that it lacked the major features people will be looking for.
The only feature I personally would like to use that it doesn't have is the ability to configure the router as a VPN client.
Thanks for the link.
