The "unconvergence" age

Everything is cyclic. In business and technology we see it all the time. We push, push, push and there is a point where the market stops us as saying "that's just way too much".

The convergent device has been great. Being able to integrate phone with PDA and then being able to GPS locate and email almost everything on the device is just fantastic.

However, I find myself more and more in a situation where I would rather prefer a second device, an example is when I am driving following a map and suddenly somebody calls.

The question here is how do we approach this? I can think of three basic solutions:

1.- Better and smarter peripherals. If the audio interface and a second display on goggles could be an option, maybe -and just maybe- we won't need a second device.

2.- The dedicated device collection. We tried this, and while we somewhat like it, it is not the Holy Grail. Carrying a collection of dedicated devices is not a good answer.

3.- The second, multipurpose, connected device. One is not enough? Try two! Not a brilliant idea but if we can limit the number of devices that we carry to two, and both can do everything we can dream of, we also get redundancy. To some extent this is happening with the arrival of the iPad. In fact many appleheads just think in "number of Apples I own". Good for Jobs, that is Steve Jobs.

4.- The interactive environment. Let's expand on concept 1. Turn your car into a peripheral. When you sit in your car, your device works like a security token and information is shared. Suddenly you have access to the map on your personal device and display it on the dashboard, or your phone can use the car stereo, and the car marks your calendar for the oil change. To some extent we are there. Now expand that thought to Home and the big screen TV, or the office's keyboard, mouse and monitor and desk phone.

Whichever way we go, the key here is to establish the real, secure Personal Area Network. Is Bluetooth ready for this?
