pricing I think pricing is the key here.. although not 'explicitly stated' Optimum Online's advertising seems to suggest that you can get Optimum Online Internet for $29.95 for 1 year
without any other service (but once you read the fine print it does say you need to be a tv customer...)
But are they 'relaxing' this restriction? Can you really get a $49.95 service for $29.95 with a year contract?
If so, cablevision is responding to $14.95 dsl as capped cablevision is about as reliable as the 768 or 1.5megabit dsl... in all reality with the caps on cablemodem usage.
