An affordable, wireless LAN is a good idea catching on fast in companies and homes. Now this is portability. I store files on the corporate network at my desk, then pick up my laptop and head to the conference room, where I use it for a Web demo.

And I do it all without connecting or disconnecting a cable. Granted, the sort of wireless communication that lets you get what you want, wherever you want it, is well off in the future.
