Some of this is almost like in old times, when writers in Mac magazines looked down their noses at PCs, and PC magazines did not even mention Macs.


But seriously, it is really a problem of suitable ergonomics.
As I see it, a cellphone and a pocket computer want quite different ergonomic solutions.
Perhaps iphone and a couple of other touch products have found a working compromise.

I want a one-handed phone, and I want to make calls without looking at it.
An interface to the contacts database that works really well without looking has yet to be developed.
If you like me prefer some tactile feedback, buttons are preferable.

The more often you want a computer without carrying a laptop or netbook, the more unsatisfying a smartphone becomes.
A phone has to be small for one-handed use.
A pocket computer can't have enough screen real estate, and it needs a more complex input interface which easily gets in the way of efficient one-handed phone use.

So I carry a phone and a NIT.
I miss syncronising calendar and contacts between them.
And I hate carrying two gadgets, but a 4" hi-res. screen is my absolute minimum for photos and comfortable enough for e-books.
