It should be useful for someone with a lot of storage or a media centre who wants to stock up on HD as I imagine would be the case with you Rik and the 6.5TB, but beyond that my only remote interest in the upgrade is that my 20M might actually go faster than 6 at peak times once the overlay is done.
I am curious though, what are people on 50Mbit, nearly all of whom are no doubt largely using it to leech HD video, going to do when they run out of stuff to download?
I'm not interested in the rights / wrongs, I don't care at all what you do with your service
just interested in what people are going to do when they run out of HD stuff they actually want, download stuff because it's there?
EDIT: Quick note, I'm not saying higher speeds are pointless I'm a huge fan of them, just that higher speeds with the crappy upload VM offer on them are pointless beyond leeching HD. I'd welcome views and experience from people who have the service to educate me a bit that's all!
