Very interesting these devices.  I've always hated mobile phones with all the apps not working together at all.  There are some great apps for specific uses, but I don't think mobiles are very productive at all, just time suckers mostly.   however, I do use a phone for ready emails/documents, which I think would be pretty difficult with this device, only having text to speech.   As a dev, I need to see apps and webpages while on the go, so this device would not help with that. Interesting none-the-less.
