Get the International Pocket Briefcase by Levenger. I put off getting one because of the price, but eventually bit-the-bullet and bought it. I've never looked back. There is nothing easier to jot notes down on than 3x5 cards; and the international pocket briefcase by Levenger can hold a good stack of them. I've been very pleased with it. If your husband jots his ideas on both 3x5 cards and 8x11 paper (as I do), have him check out my David Allen folder "hack" for creating the Perfect Portable Inbox for both paper types.
