I like to keep a folded piece of paper containing a few post-it notes in my pocket. You never know when you are going to need to leave someone a message or take notes for a phone conversation. It’s nice to have the post-its that you can stick on a wall while you write, and the folded paper for longer term notes. I have a PDA but I’ve found that while it’s great for scheduling, it sucks for taking quick notes... especially when you have a cell phone in one hand!
Behold the little piece of brilliance known as the PocketMod. It’s basically just a slick way to fold your note paper to make it a little book. It’s also customizable with different lines, calendars, and games that you can print on each page. It’s innovative, functional, useful, and free. I like it!
