Well I've been looking at their site, as ya do and this is what I found:
Speed*
blueyonder 1Mb is up to twice as fast as a standard broadband 512kbps service and 20 times faster than dial-up! The downstream speed is now 1024kbps, so downloads are now faster than ever before. We've also increased the upload speed to 256kbps to help you share or publish large files faster.
Email Accounts
blueyonder 1Mb provides five email accounts, each with three different email aliases.
Priority 1Mb Freephone Technical Support
Priority access for 1Mb customers to freephone technical help and advice 7 days a week, 24 hrs a day.
Personal Web Space
You have access to 30MB of space to build a web page devoted to photos of you, your dog, the band you were in the 70s or whatever!
Price
The blueyonder 1Mb service is now available across the country in Telewest areas.
If you are a new blueyonder broadband Internet customer, there is a one-off installation fee of £50 (or £75 if you require an NIC card).
Unlimited 1Mb access is then only £35 a month if you take another Telewest service or £39.99 if you take blueyonder Internet alone. This is only £10 per month more than our 512kbps broadband service for up to twice as fast Internet.
