I wrote earlier about the one or two box solution to mobile data and communications.
I now have both the Treo 650 and the Sony Ericsson P910i and they are similar but different and at this point the main difference for me is the number of hands required to use them.
The Treo 650 has a very polished user interface that allows you to do anything of the device with just one hand whereas the P910i is definitely a two handed device requiring use of a combination of stylus and jog wheel.
I’ve only had a hour or so of play with the P910 but I’m struggling a little with the UI.
More to follow…
