The Phree is an interesting device that will probably be very useful to a lot of people. The Phree is a pen that can write on pretty much everything and input the data to a mobile device. So you can picture it, look at the armrest of your chair, get a pen and write.
Whatever you just wrote would be sent to you phone or tablet just like that. You could be at work, taking notes during a meeting without needing paper, at university and quickly want to jot down some advice without taking out your phone or laptop. If you need to get it written down right now, the Phree pretty much makes that possible via Bluetooth connection.
