Long rumored to be offering a faster broadband plan, Comcast has pulled the trigger, introducing a new “Extreme 105” service tier offering 105Mbps down and 10Mbps up. The price for this, if bundled with its Triple Play plan, is $105 per month for the first year. The coverage area includes a span of 40 million people, in places like Baltimore, Chicago, Denver, Miami, Philadelphia, Portland, San Francisco, Washington DC, and most of Boston, with more markets to follow.

As for whether Comcast plans to lift the 250GB data cap for Extreme 105 customers, the company hasn’t said. Likely, it will be this same ceiling that it imposes on all its other broadband customers.

Full disclosure: I am a Comcast/Xfinity subscriber who rarely sees the max speeds promised by my plan, so excuse me if I’m a little jaded by all this. (If you’re not… um, well why aren’t you? Kidding.) Realistically, even if the speeds promised do show up in the real world, I’ve got to wonder how useful this will be if the same limits are imposed. All it means then is that people will reach their caps faster, right?

What do you guys think? Is this plan worth the extra bucks? Or, if you’re willing to super-charge your broadband anyway, would it be better to just upgrade an additional $40 for a business class account with no limits? Let us know your thoughts in the comments section.
