Update: Charter will be all-digital in my area as of May 1, with a gradual rollout in the entire state during May 2014.
The latest quote for the digital box is free for the first year (if you complain), then $6.95 per box, per month thereafter.
They claim that basic cable rates will not increase for now for residential customers. However, commercial customers will get a near-doubling of their basic cable rates in May.
To offset the increased costs, they will be increasing the maximum download Internet speed to 60Mb/s (from 30), but not increasing the max upload speed, which will remain at 4Mb/s. That means if I transfer data from one Charter customer to another, the fastest I can go is 4Mb/s, and the download speed is inapplicable.
