Are you one of those people who collects stuff? Not material items, but little tiny scraps of information, be they photos, places, products, text snippets, ideas, or plans? Then maybe, maybe, you should try Springpad.
Springpad is a free iPhone app in the vein of Evernote, except with a broader scope. You can dump just about anything you encounter in here: photos are easily snapped and categorized; barcodes are scanned and filed; restaurants and stores are identified by manual or geo-based search; notes are pecked and saved; every input field, nearly, is augmented by a "search" option; and all your material syncs to the service's desktop web interface.
