we can bury our cb2 boards.
No need to bury working hardware, I still have a cb2 in use!
But not with LE (it's too weak for that anyway), but with OpenWRT. You don't have to use it for wifi/routing though, it has a huge package collection.
So my good old cb2 is a mpd client on OpenWRT playing music. And then there's my good old beaglebone, which runs asterisk on OpenWRT handling my phone calls. Both rock stable without hiccups, doing their job and while barely using any power
