Having said that, I'm not sure about the other stuff. I actually like going out into town and buying my groceries. It's social interaction, it supports local shops, it's a great way to get to know the place and the people. I could easily sit in front of a computer, pull up Tesco.com and order stuff in, but it's not the same. I'd actually question whether that's even "living in the cloud" - surely it's just internet shopping as it's been since about 1999?
The same goes for radio. Yes, you can switch on Spotify, Pandora, Rdio or any one of those services and hear your favourite songs, non-stop and commercial-free. But who introduces you to new artists, who gives you news and opinion, who provides the bits between the songs, tells you what's happening in town that weekend, tells you when the road's closed? Spotify is just your musical bubble, in a long, boring loop. I couldn't live without my radio in the room. (Disclaimer: I work in FM radio.)
The cloud is great, the cloud is an innovation, the cloud is very useful for many, many things (I use Dropbox, Google Docs, iPlayer, and so on heavily.) But to move your entire life online? I work all week sitting in front of a PC. I couldn't transform my free time into that too.
