Sure, depending on your area. In my area, no. Their current infrastructure is not capable of supporting 30/1.5 in Bristol at the moment because of the sheer volume of traffic, created by their large increase in customers.
130 million for upgrades is great, but I should imagine that initial upgrades MAY fix things by increasing capacity. But as soon as the 60Mb rolls out (Which to be fair won't be for ages in Bristol - we've been waiting for the upload upgrades for a long time) the problem will revert back again.
It's simple numbers really. The total bandwidth available across Bristol is currently considerably less than the total of everyone's connections. Even friends from work who have 50Mb suffer the same issues.
When 30Mb works, and works properly, I wouldn't consider needing any more bandwidth. There's nothing you can't do with 30Mb and downloading large amounts of data is not exactly slow.
I simply find the entire thing rather pointless and a big PR stunt which will continue bandwidth problems in my area.
