Ask HN: How do you record your thoughts?
Some of my own ideas as far as devices:
* Pencil and paper - Pros: Lightweight, flexible. Supports illustrations and complex layouts. Cons: Hard to edit or search retrospectively. Low bandwidth text entry. Requires space to store. Easier to lose/damage than well-backed-up digital content.
* Laptop (e.g. MacBook Air, MacBookPro, or EeePC) - Pros: Fast text entry. Searchable and editable content. Cons: Unpleasant to carry around everywhere. Illustrations and complex layouts are awkward.
* Tablet - Pros: Fast text entry. Supports illustrations and complex layouts. Searchable and editable content. Cons: Unpleasant to carry around everywhere. No Mac tablets.
* iPhone (or G-1, etc.) - Pros: I've always got it with me anyways. Content in searchable and editable form. Cons: Low bandwidth text entry. Very small display area. Illustrations and complex layouts are awkward.
