I gave in and bought one a few weeks ago.Booted it once to check the hardware, then reflashed with Linux and SFOS. Ive booted linux a couple of times to play with, but otherwise its my daily driver phone.
I've noticed a few issues, but its at least as good as the X was running the community port.

Hoping the external button will answer calls in SF3...
Had a couple of random reboots while in standby - due to current restrictions when it comes back its running android, otherwise I might not have noticed.
Keyboard is great.
Failed to find a decent carry case. Planets own offering looks like it might not be as protective as I would like. Waiting on a custom case from a chinese ebay seller Ive used before.
Some apps dont like the super wide landscape screen e.g.Stellarium
Forum pages often dont render properly in the browser, too wide for the screen and wont scroll or zoom out.

Pretty minor stuff all in all - Roll on SF3!
