This is an excellent personal organiser. You can do all the usual stuff like editing word docs, excel, games, emails, diary and it has an added bonus of a camera which is always fun!
The navigation is fab if like me you get lost quite easily (and others will be jealous!). For a price much less than an in car navigation kit you get a great PDA and bluetooth gps. It tells you exactly where to go and if you go the wrong way it recalculates your path. Also you can pick anywhere from an overall map of the country by zooming down if you don't know the street name etc.
