Yeah, there’s a Notes application in your iPhone, but let’s face it: no one uses it. Well, some people do, but there’s no denying that there still exists a strong contingent of people who haven’t lost all love for hand writing. The iPhone Paperback Notes consists of 80 sheets of self-adhesive paper that stick straight to the back of the iPhone 5. Write stuff down, tear that sheet out and stick it somewhere like they used to do in the 90’s. It’s $8.
