Wouldnt it be possible to do the same through an iPod or iPod Touch? Given that the joojoo has no keyboard or apps, there isnt much of an advantage except for the screen dimensions.
I've been thinking of a product that could use a prepackaged webserver on the users home network, (or a or an Internet service) to provide a calendering and home organization service on the a users home system and this would make an ideal interface for a kitchen/bathroom/hallway.
If only it were at the old promised price-point.
