I read this topic recently which a lot of wifi hotspots were being put up. Do you think one day the world will be so full of wifi you won't need internet hooked up in your home?
I think once Satalite internet becomes more fast, popular and affordable or free because of earnings from Advertising like Google Ads, Adbrite, pop-up ads, etc earnings then we won't need ISP hook up to our house.
There are RV, buses, planes, and limo which have internet via Satalite, but it is expensive. I believe the US Army uses Satalite internet, so the Army can communicate with the president worldwide.
