Selling VDSL to your average broadband customer was always going to be tricky.
For starters, DSL has this reputation of not delivering what is promised, which unfortunately due to the nature of the technology is partly true. This of course is why its being sold as "fibre" broadband, sneakily hiding the VDSL aspect entirely, to try and convince people its better than what they are used to.
But there are a lot of people who treat it like they do voting "Why bother, they are all the same!". They are wrong of course, but they are the kind of people its VERY hard to convince otherwise.
I do not think "what I have now is good enough for me" is quite as prevalent as people think either. I think the problem again is that people are used to YouTube stalling, gaming being crap (so much so games are written to perform WORSE on low latency connections now, how stupid), things just generally loading like sludge and they "think" that is normal and they can't get any better than that.
Its not helped by BT Retail either, with these silly adverts proclaiming the HomeHub as the second-coming of christ. No BT, the HomeHub isn't going to allow 10 students to Skype chat to their boyfriends simultaneously over WiFi, even on VDSL I doubt WiFi is up to the task there as the overheads of so many devices at the same time will be shocking. I'm not aware of any techie who would be caught dead using a HomeHub, because they really aren't all that good. What they SHOULD be pushing is that the broadband itself allows these things, but no its all about the HomeHub. So when someone buys the product and can't even get the WiFi for a single device to do full speed, its not going to make them feel like promoting the service to their friends.
