43Folders presents the Hipster PDA:

“…The Hipster PDA is a fully extensible system for coordinating incoming and outgoing data for any aspect of your life and work.
Let’s make one together:

1. get a bunch of 3″ x 5″ file cards
2. clip them together with a binder clip
3. there is no step 3

From the 43Folders Wiki* :

“There are a number of benefits to a Hipster PDA over a digital PDA:

• Cards can be arbitrarily resequenced, given away, and writing by hand is freeform and unrestricted
• Won’t run out of batteries
• More durable
• Cheaper
• Information doesn’t get lost in there; when something’s no longer relevant, you throw it away
