Newsgroups - never used them.
eMail - gave up on it months ago. All our ntlworld addies have long since been redirected to our excellent @mac.com account.
Webspace - never used it. My Apple iDisk gives me 100mb and integrates seamlessly with Mac OSX for publishing our family homepage.
I'm currently paying £25 for 600k down/128k up. I'd love to get 1024/256 for the same price. However I (reluctantly) don't think it can or should happen. It can't, because ntl can't be seen to be offering less than the competition - Joe Average Punter knows little about these things and throwaway statistics about the number of email addresses you can have sounds impressive. It shouldn't, because Joe Average Punter shouldn't have to go setting things up separately all over the place. The internet is meant to be getting easier, not more complicated.
The blatantly obvious solution would be for ntl to get its act together. Whether they will or not ... well, I'm waiting to see.
