Considering the amount of time people have these tiny devices in their hands and the variety of uses they make of it, I tend to see them evolving more as a 'friend' or even an 'alter ego'.

Science fiction always thought about technology becoming our friends or alter egos in the form of humanoid robots, something between R2D2 and C3PO. However, what was relevant about those robots was the fact that they could tell and show you many interesting things, travelling always with you and introducing you to new beings and new worlds.

I hope Maemo 55 will become my R2D2 replacement.
