If you hate the idea of being away from Twitter, the Twitnote Magnet Set can help to make real life feel a bit more like Twitter. Just jot a quick note down, 140 characters or less is optional here, and wait for a response from someone else in your house.
The set gives you 6 magnets, the largest being the Twitnote. You also get a pen with eraser that will allow you to write messages and erase them, again and again.
The other magnets include things like the fail whale, the “t” button, twitter bird and the robot. The set is just $34.90 from etsy seller bloopystore.
