Why is everyone moaning about two-tier internet speed etc. A few years ago (and maybe even today), with ADSL you could pay £x for upto 2 Meg, £y for upto 8 meg. It meant ISP's could charge for the geeks downloading movies etc (cos back then, only they really knew how) and break even on Average Joe and Joan just surfing and shopping.
This is what will happen again. You want fast speed, pay for it. It's the same with cars. You get the cheap Smart ForTwo and can only go upto 60mph or you pay big bucks for a Porsche 911 which can go more than three times that.
As long as ISP's give a realistic choice it's not a problem.
