The worst part, is not -knowing- your data was stolen. If someone steals my wallet, I know it is gone, if someone copies your data, you don't know it until they use it.
As far as cyanogenmod, you will also want to make sure you have a supported phone first. IIRC they chain the bootloader, use the same kernel, and drivers, and a new rootfs.
Some of the arm platforms aren't terribly well publicly documented, it is actually an issue getting linux platforms working with some hardware. There has been quite a bit of standardization between the hardware, bootloader and kernel, making it easier and less quirky which should impact both standalone linux arm, and embedded devices, making it easier for everyone moving forward. Plus a lot of bugs have been fixed and even some logic errors like alignment issues.

For starters, you have to forget the base image that ships and go with something like aosp or a cyanogenmod base. Then, be very careful about the perms you grant apps, in particular phone identity.
