What about the high street, CD, DVD's BluRay, stores that sell these will cease to exist.
This is a ridiculous statement. Stores that sell those items will just have to adapt or miss out. People didn't resist moving to cars because they'd eventually put the local farrier out of business. Holding back advances in technology to save an outdated business model doesn't help anyone.
I would much rather buy from an online store that keeps a record of what I've bought and lets me re-download it whenever I want even if that happens to be in the middle of nowhere over a mobile connection than fill a shelf up with boxes.
