Hipster PDA

The Hipster PDA is a paper-based personal organizer, popularized by Merlin Mann in 2004.

[1] Originally a tongue-in-cheek reaction to the increasing expense and complexity of personal digital assistants (PDA), the Hipster PDA (said to stand for "Parietal Disgorgement Aid" and often abbreviated to "hPDA") comprises a sheaf of index cards held together with a binder clip.

[4][5] Although it began as a joke, or perhaps a statement about technology fetishism, the Hipster PDA rapidly gained popularity with serious users,[6] with hundreds posting pictures of their customized hPDAs on photo sharing sites and exchanging tips on Internet mailing lists.

Advocates of the hPDA claim that it is a cheap, lightweight, freeform organizer[7] that does not need batteries and is unlikely to be stolen.

Enthusiasts also design and share index-card-size printable templates for storing contacts, to-do lists, calendars, notes, project plans, and so on.
