Thank you all for contributing....I'm still deciding if I want to bother with this or not.
I also can't buy the argument that this is to prevent people from 'trying out' the speed and then getting rid of it......there's a 12 month contract required and a fee that will hit you if you try to break the contract early, so that doesn't explain the 250.
If it means a tech has to stop what he's doing and investigate that speed their immediately however.....if the 105 isn't up to snuff...that is sort of another story, that is like "Priority Service" in a sense. But if you have 105 and service is flaky and you still need to wait 12 days for a truck to get sent out...well.
Still hemming and hawing.....
