If you've ever owned a laptop, you know the experience of being "out and about" and unexpectedly noticing that you're able to receive internet access. Getting "wi-fi" is happening more and more in airports, coffee shops, and certain restaurants across the country. It's certainly made my flight delays more tolerable from time to time.
However as more businesses realize the potential draw of such a service, combined with the relative low cost of providing it, you'll surely see more in the future.
That's where
JIWIRE.COM comes in. They provide a search-able database of local wifi "hotspots" for your internet pleasure.
