In Search of the Smart Phone Laptop

In the past two years, cell phone and laptop companies have unveiled breathtaking innovations -- from 24-hour battery laptops to dual-screen laptops to "augmented reality" cell phone applications. Despite these advancements, the industry has failed to solve the oldest and most central problem of mobility: How to add a larger keyboard and screen to a tiny cell phone. Palm tried it and failed with Foleo. AIM proposed it with Olo. Apple hinted that they might take a crack at it. Celio is already doing it -- but you need an approved Windows Mobile device. And IMOVIO is working on a solution doomed to failure. WHO WILL GET IT RIGHT?
