"mp3 player with cassette adapter" I use one of those too!
I envision us all having internet radio in the future, but corporate and government forces are fighting WiFi. There should be free or next to free WiFi everywhere a cell phone has a signal now, either government subsidized like utilities, or provided privately at a reasonable rate <$20 a month. Satellites could feed the entire country with internet as well.
It would be worth it for the government to provide this as a utility, because of the economic progress and technical inovations this would stimulate.
We can barely imagine what this would mean. Every device could come standard with a NIC and an IP address. Cameras would sync with your pc, and web site instantly. Your car could email alerts. Your house could turn on the lights and unlock the door when you are in the driveway. It is unlimited. Free unlimited phone calls via voip.
Of course the phone trusts are opposed to this, the government won't be able the trace IP addresses and do phone taps, and the RIAA MPAA won't have anymore cases without ISPs to supena, but overall it would be progress!
