Couple general comments (and questions to current X2 users):

The design of the x2 technology (see x2.usr.com for the white paper on it) gives the doubled speed on the downstream because it isn't getting an analog to digital conversion at the trunk - the difficulty of a user getting a 31.2k connection over a 28.8k is about the same as getting a 52.8k connection over a 48k.

Question for the x2 users - what kind of UPSTREAM connection rate are you folks getting? If you're getting 48k rates, that's suggesting that your upstream rate is 24k - do you get greater than 24k if you use a straight v.34 connection mode?

Cable modems will be big stuff when they move into your town.. but don't expect them to be useful long term. A friend of mine who has used a cable modem (in Europe) for 2+ years had great experiences with it when he was one of the few subscribers on the system, but as the consumer moved to wanting internet connectivity, his performance has steadily dropped. A 10mbps line sounds great, until you subdivide it with 50 of your neighbors.

We should expect net throughput to continue increasing over the next few years, but we'll mostly be seeing it in incremental technologies (x2, k56flex) and cable. Use this incremental technology now and be happy with it, and welcome its obsolecense in a few years.

Speaking of K56flex - keep in mind that it's coming too (it's the rockwell / lucent standard) and offers a couple advantages over x2 (more widespread ISP support, higher speed upstream path, and probably a better chance at receiving the ITU-IT standard - we all remember what happened with v.32ter vs. v.FC).
