Thanks folks, for the friendly suggestions - I'm going to look into the details over the coming few days.

I'm getting the power thing resolved but wondering what the best option would be for VOIP and web browsing. Seems that Skype never came to the 770 in a useful form but this OpenSky(pe) thing from Gizmo may work.

Hopefully there are some good wifi options around there...I've spent so much already on flight and train travel!

I guess I'll do what I have to do. :-)

Mahalo to the Maemo community!
