If you all want to join PCXX 30M and using Vista, pls be careful.
I used speedtest and knew that only with speed 11M(sometime 9M only). I called them for checking and the technical person said that Vista user will have this low speed problem. And the company don't have any software to improve this status.
I joined the 30M program($238/mth) because of my 8M contract terms end. The sales didn't mentioned would have this Vista's problem. Even after checking, they are not allowed me to downgrade to 8M program and said that this is only due to my computer's problem, not them.
