Wi-fi set to re-wire social rules [BBC]
The buddies you have on instant message networks, friends and family on e-mail, your eBay auctions, your avatars in online games, the TV shows you have stored on disk, your digital pictures, your blog – everything will be just a click away.
It could also kick off entirely new ways of living, working and playing. For instance, restaurant reviews could be geographically tagged so as soon as you approach a cafe or coffee shop, the views of recent diners could scroll up on your handheld gadget.
Key to the transformation would be mobile devices that can use wi-fi. These handsets are only just starting to appear but will likely cram a huge amount of functions into one gadget.
