All these offers are shaped, with no real details of the shaping. I think we need a standard program to perform a set of benchmarks for various ports, protocols, etc., using a standard range of servers. Then the ISPs can, of course, start tailoring towards the benchmarks
I think someone who signs up for one of these uber-cheap uncapped services and expects to do continuous YouTube, torrents, etc. is going to be bitterly disappointed. Hopefully MyBB or other sites can start digging into real comparisons of these offers.
I had an uncapped Uninet 128k service years ago, and, trust me, it was useless.
