last .. I hear you .. But do you think that degree of specificity would fly here? LOL. Moreover, that is too easy .. terms should come into the picture. I'm reminded of an insurance company that nearly went under because they decided to pay their salesmen based on the projected future premiums of new policies with no regard to the credit worthiness of same. Of course, they got an overwhelming rise in new policies as the salesmen tried to sign up every warm body in sight. This was followed by a large failure rate not long after the salesmen had cashed their checks.
I think you will have a choice:- a computer that you can use as a mobile phone or a mobile phone that you can use as a computer.
The difference is that the PDAs will be bigger with a bigger screen which you can put in your pants pocket and the handset you can put in your shirt pocket.
