I do get a nostalgia feeling though as they seem to not understand how to do marketing with modern social media etc :-).
Really? I'm not into CUSA myself and would probably never buy from them, but they've made much more marketing ground than Hyperion/A-eon/Acube or Genesi. I've had two friends so far who have zero interest in the Commodore/Amiga but know I'm into retro stuff contact me with links to CUSA. That's never happened with regards to OS4, MOS or AROS.
CUSA is on Facebook, don't they also have a Twitter account? Hyperion doesn't do this.
