Let me just chip in. I'm a Freenaute too, but i moved from Poland having a UPC (docsis 2, then docsis3) connection. The difference is astounding. Using ADSL2+, the top i can get is 28MB/s, but realistically nobody gets more than 12MB/s (on average) because of the distance to the DSLAM, which tends to be 1km-2kms. I get 10. Is there a way to fix that? No, because Cat3 can't carry frequencies above 2Mhz at that distance.
For comparison, i get 50MB/s back in PL without the line ever breaking a sweat, and if i wanted to i can upgrade to 100MB/s (i haven't since i don't have a router *at home* that can handle the traffic) on a whim. And why? Because with a copper shielded cable the cable doesn't experience interference, and the width of *one channel* is more the total bandwith of one ADSL line.
I really get that for an ISP, Free is trying really hard to make ADSL suck less (by not using PPP for example, all the extras), but from personal experience Docsis > ADSL any time.
