Same deal here. CB sent me an email telling me about "Great news" that ZT Max was now available to me...10/768k for $10 more per month. I'm a Charter Member meaning I've had ZT since it was available and at the end of 2010 this is the best they could come up with?
I immediately called Insight and in 2 days I'll have their new 50.0 service (50/5). I can't see myself going back to CB even if/when they offer fiber here. They've treated their customer base too poorly for too long.
