Yes, I'm on it!
Signed up about a month ago for the 3mb service, and after some initial problems that have been resolved now, it works well.
I was suffering a lot of packet loss but now this has cleared up with just some fluctuations throughout the day as to be expected.

Downloads are quick compared to my 512k ADSL connection, get between 2-3000kbs depending on time of day. Gaming (when theres no packet loss problem) is fine, race in an Online league and that is very smooth, smoother than my ADSL ever was, not sure about Counterstrike but I imagine that to be the same. Pings to jolt.co.uk are about 25ms.
Installation took about an hour.
Customer Service is great, theres always someone waiting to help at the end of the line and emails/tickets have been dealt with effieciently. I did register before the service was available and they didn't reply to tell me when it was available, but this was minor.
Not sure how many people have signed up in this area of Thanet, but I've seen a few houses around with the required aerial so it's getting customers.
I think its a great service for those on the edge of the ADSL service, like our village it's perfect, and thats what the service is aimed at.
Only thing I see now though is that MaxDSL is here at a lower price, so I'm wondering if the speeds for SoBroadband will be increased in the coming months to stay competitive (not that I need anything more than 3mb!)
Any questions, just ask.
