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 while on the go.
A new IBM survey of 600 desktop PC users in the U.S., China and the UK says most users would be willing to replace their PCs with smart phones for using the Internet. Some 71% of respondents said they plan to increase their use of social networking, instant messaging and reading the news on mobile devices.
The study found that a large screen and large keyboard - mutually exclusive features on a handset - are among the most desirable features for mobile Internet access.
IBM advises in its report that "device makers need to think about how to integrate technologies such as nano projectors and projected virtual keyboards." But this advice probably reflects the direction of IBM's own research rather than actual demand on the part of users. I believe users want real big screens and real big keyboards, not projected or virtual ones.
Palm inventor Jeff Hawkins tried to solve this problem last year by proposing the Palm Foleo, a Linux-based mini-laptop that would have connected to the Internet via a Bluetooth-connected Palm smart phone. And what did he get for his trouble? Scorn and ridicule.
The Foleo had its own processor and memory, as well as generic office applications, browser software and e-mail application. It was an "instant-on" device usable seconds after being switched on.
The Foleo was roundly criticized for being too expensive ($499) and too inflexibly dependent on the use of a Palm phone while at the same time unable to actually run Palm applications.
Suddenly, however, the general goal of adding bigger screens and keyboards to cell phones has come back in the form of rumors, projects and even real products. It looks like the industry may be serious this time. But will users buy?
Here's what's going on.
The AIM Olo
A rumor circulated recently that a company called Active Innovation Management was working on a laptop-like gadget called the Olo.
The concept showed a sort of dock in front of the laptop's keyboard where an iPhone fit with the iPhone screen flush with the surface of the plastic. Once snapped into the dock, the laptop would actually use the iPhone's processor, memory and other resources as the "brains" of the laptop.
The product sent a ripple of chatter through the blogosphere, prompting the company to post a statement on its Web site saying that the Olo is nothing more than a design concept.
In hindsight, it's pretty obvious that this was always a product without a future. It's just not Apple's style to open up their APIs to some obscure company for building what is essentially competitive hardware. Something like this would come from Apple, or from nobody. And speaking of something like this coming from Apple ...
