The Nevo C2 is more cable than most low end Harmonys over all and uses the far superior Remote Master software for configuration. Best of all, it's only $16. See my Harmony comparison below:

Realize that if you want to control your PS4, your options are limited to Harmony Hub based remotes.

The latest Harmony software is much improved over what you're using for your 1100. The Elite is an excellent Harmony remote with far more capabilities than your 900.
