Simple idea
  This is a really simple idea, but worth thinking about if you're starting a new company over the weekend.
  Here's how independent bookstores can compete more effectively with Amazon. Install an AirPort. We bring our laptops to the bookstore. Research books using Amazon's excellent community features. Buy them at the local store. Instant gratification.
  Plus, think of all the cool proxy-server-based apps you could do for an on-location wireless LAN. It could put a frame around each page and allow you to quickly see if the book is in stock and what aisle it's in.
  This idea would work not just in bookstores, but in any kind of retail environment where better information meant greater sales. Plus people could check their email, so they'd like you better.
  This wireless stuff is really interesting!

  PS: I'm sure 18 companies are already working on this.
