I am in the process of buying a N800 (previously had a 770), I mainly want to use the tablet foe mail, browsing, RSS and more importantly as my primary GPS unit. My question relates to the OS2008, this will have the GPS app and maps, will I be able to use the GPS app on the N800 using an external GPS receiver, will I be able to purchase the premium maps so can use the voice navigational services that I currently use on my Nokia cell phone?

Thanks for your help
