My favorite feature of Cyanogen now is that they have Whisperpush enabled by default, which secures all text communications from a Cyanogen phone to another or to a TextSecure app.
I hope they will be willing to integrate RedPhone by default in it, too, eventually.
As someone who's more technical, I don't necessarily "need" Whisperpush, since I could just use TextSecure directly - however I think it's great that anyone who would be buying this phone would have secure communications by default (without even having to care about it - which is the brilliance of it), and the more people buy it the higher chance they will be communicating with a TextSecure user (or with another TextSecure federated client, since I think you can use the TextSecure protocol like you can with OTR).
Last I heard, Whisperpush on CyanogenMod only actually worked if you had the GApps package installed which isn't entirely legal and certainly isn't something they could get away with including as standard.
The best disclaimer sentence I've found here is: The Google Apps packages are NOT SUPPORTED in any way by Cyanogenmod. Not exactly a huge endorsement, but saying it's not entirely legal is something else entirely.
It depends. If you are installing CyanogenMod on your phone, then installing GApps is not very legal. However, Cyanogen team has been working with Google to get devices like the OnePlus One certified by Google and preloading them with fully legal GApps package.
