forget the blackberry, sometimes you just need pen and paper to get things done. Memo pad easily fits in your back pocket as you write down errands or other bits of information on your "to do" list daily.
I'm a less-is-more kind of person and needed small note pads to carry with me in my daybag. These are simple and old-fashioned, but the wires don't come undone no matter how much abuse they take lurking in the bottom of my bag. Good product.
I love using memo pads when I'm in the lab for quick calculations. The pages don't adhere together which is found in the cheaper ones you can buy at your local drug store, and the wire binding isn't too small for the pages to turn. These Mead memo pads are great.
