Nice unit.
The only thing I would recommend (as you are a current user) is to check if there are any VGA updates available of the programmes you already use.
Also have a look at the VGA ready apps thread in this forum.
Enjoy your new 'toy'
With regard to changing over.
If yoiu already have AS3.8 installed - connect the cradle, out your iPaq in its slot, create a partnership and then copy your old MyDocs files into your new MyDocs directory and they will all be available.
BTW - you won't need you Wifi CF card anymore
