Okay... First thing's first...
The screen is not similar to the Cassiopeias and Jornada's with STN displays.
The screen is of the transflective variety although not as good as that on the current iPAQs.
I have one with me and I've been testing it for a couple of weeks now.

The size is just right... it actually feels more like a smartphone than a PPC Phone Edition.
The screen is not as reflective as it should be nor does it posess the crispness of the iPAQ screens. But as a phone, it does offer more than most smartphones around.
The built-in caller picture ID app is much better than those offered by 3rd party developers... and it really works!
The camera isn't good for taking photos (you can see the sample of one photo in the link above), but is ideal for videoconferencing or for using the P300 as a video phone although I'm still looking for software that will work with it.
Battery life is wuite good and outlasts my Tanager. It's metering though is a bit odd... It seems to show a quick decrease in battery charge but lasts quite a while from 50% down giving an acceptable battery life.
It's not at all that bad and considering that it is priced at abot half that of the XDA II, then it is worth considering... and if you need more convincing... what would you rather have a $500 phone or a $500 Pocket PC Phone Edition?
Mabuhay! ~ Carlo
