I have looked at the HP 4150 and the Dell X30, both of which have bluetooth (I have a bluetooth GPS) - or should I go for the iQue with built in GPS (no removable battery!)?. I wish to travel on foot in foreign cities (battery life) and have voice navigation in the car. It would also be useful if it would talk to my Nokia 6310i for eMails and traffic updates. As a Mac user I have no idea about PC type things but it seems that memory will also be an issue to hold the required maps. Any suggestions appreciated.
