150 Mbps, you're lucky.  Here AT&T has to bond  2 pairs so I can get 25 Mbps.    At least it's not comcast.  I wonder how many pairs they could bond.  Is there a technical limit or is it just a matter of how many they want to bond?  As more people abandon landlines, that leaves more capacity for AT&T to bond multiple pairs for internet customers.
