Nothing can replace the notebook.
Even though many people carry laptops, smart-phones and other electronics with them everyday it seems that the old pen and paper hasn’t been completely abandoned. Nothing beats the free form ability a notebook allows when jotting down a note, idea or inspiration.
Here is a brief list of some of the more interesting notebooks I have come across recently:

The design of this notebook is inspired by Behance’s Action Method.

They offer a family of notepads inspired by various historical moments/people of design.
Le Modular is inspired by Le Corbusier.

The Guardian is inspired by David Hillman’s redesign of the Guardian in 1988

I have been hearing about a new notebook call Field Notes. I haven’t seen one and am not sure what sets it apart from others. But people seem excited.
On their site they have a good quote:
“I’m not writing it down to remember it later I’m writing it down to remember it now”
And of course there are the classic Moleskine notebooks.

I am currently carrying one of these around.

What do you carry?
