You can write a huge list of reminders on your phone, but you'll still forget them all if it's tucked away in your pocket. That's why sticky notes have yet to be replaced by devices like the iPhone, and these app icon-themed pads seem like they're rubbing that in.
There are six different pads to choose from, loosely based on the iOS icons for mail, messages, clock, contacts, calendar and notes apps. While they're close enough to be recognisable, they're still different enough to dodge a lawsuit from Apple. $US18 gets you all six. Just keep in mind you'll definitely need a stylus to use them.
