Just a personal $0.2: this device does not appeal to me for two reasons (1) it isn't a phone and (2) it is quite lousy computer due to a limited storage.
If it had more built-in storage I would love to use it as a portable travel PC so I could unload photos from my camera onto it while traveling, review the pictures, write emails, and use it as a GPS you can walk with.
Huh? You can literally dump photos to it and just upload them across the internet to your desktop, as long as you have a wifi connection (you mentioned writing emails, which would require wifi as well).
