Reading Wil Wheaton's blog, he mentions this device. I rather like the whole idea of it, especially the orb.
Though initially I couldn't tell from the website, apparently the devices can be configured to moniter whatever you tell them to- specific sender email or voice mail messages, weather, traffic conditions for specific routes, stock prices and so on.
They also can apparently turn everyday objects into these kinds of moniters. I have no idea what I would do with one (I don't really need any of those things monitered) and they are still a little pricey for me to buy, but the concept suits the part of me that likes attractive new gadgets.
