Tinderbox is a great tool for notes, but sometimes you need paper. When inspiration strikes while you're waiting in line at the grocery or sitting with your seat in the upright and locked position, there's nothing like a 3x5 card.
But you need to have a card handy. You don't want to remember more stuff; you've got to write it down.
Eastgate's just got a supply of these nice little 3x5 card wallets. There's always a card ready to go, and there's a second pocket were you can slide cards you've already written, ready to scan or transcribe into Tinderbox. And they're really nicely made -- Italian leather, crafted outside Paris, they're thin and light and should last for a long, long time.
