Is the $39 AT&T HBO/Cable deal worth it?

It appears that there are other fees like a $7/month "Internet Wifi Gateway" that is required and $200 installation. Plus the $39 is only good for a year and then it goes up to $80 + $7 internet gateway + $7 / TV.

So it's:

$39 - base fee
$7 - Internet Gateway
$7 - Additional TV
$16.66 - Installation fee divided by 12 months

That is around $70/month for the first year.

After that it will be:

$80 - base fee
$7 - Internet Gateway
$7 - Additional TV

or $94/month

I don't think it's worth the pain and not to mention the data cap:

AT&T Data & Internet Usage Tools

You'll be charged $10 for every incremental 50 GB of usage beyond 250 GB.
