The screen size on the 770 is not larger in any meaningful way compared to a high-end PDA. Yes, you get a few more pixels, and it's 4 inches instead of 3.6, but that's just details, the experience is very similar (except when surfing, when the wider higher-res screen in the 770 makes a very real difference.)

As I said, I like both my 770 and my PDA, and use them both but for different things.

For notetaking, I firmly believe the PDA + a small foldable Thinkoutside bluetooth keyboard is very hard to beat. Sure, it's another PDA-sized device to carry but for what it gives you it is worth it.

In a meeting, I can take notes as quickly as people are speaking (I'm a touch typist) and I can input any info about followup meetings into the calendar right then and there. If there is something I'll have to do as a result of something that comes up during the meeting, I'll just input that into the to-do list on the PDA - and then sync all that info up to my desktop Outlook automatically when I come back to my desk and place the PDA in the synching cradle.

Heck, I've even used the built-in camera, crappy though it may be, to photograph the whiteboard after the meeting so I would have a record of that too to take with me and then copied that .jpg to my desktop machine to keep as a reference.
