Mobio, another of the top 25 new start-ups to watch, is building a business around creating a mobile Internet that is customized to your geographical location and your interests.

Imagine the information available on your cell phone would be customized for you based on places you've visited and things you've researched.

Both Sprint and Cingular have already joined forces with Mobio to help bring this personalized service to their users.

The company's mission is to enable the creation of mobile content and applications that are fun, simple, and useful enough to merit everyday use. Customers don't need or want to take the "whole web" with them while mobile. Instead, they want to carry with them only those bits of the web that is relevant for them given their specific tastes, interests, geography, as well as the task they are trying to accomplish at a particular moment in time.

It seems as though the businesses we are supposed to keep our eye on all relate to the Internet.

I suppose it is the last great horizon. So does that mean we've exhausted all other areas of business opportunity?

Technology is good for what it provides, but some say it is making us a population of reclusive introverts.

Personal Internet sounds cool but is also seems limiting. It's like the blinders are being put on for me, taking the fun out of discovery. I remember when I first moved to Cincinnati, each day after work I would drive in a different direction until I was lost. I'd get out my map (a piece of paper that was folded, not a GPS system) and find my way home and in the process discover new and interesting places.
