Springpad could easily be the digital version of an overstuffed wallet. Random thought? Store it in Springpad. Want to record audio? Save a bookmark? Yep -- Springpad. You can even scan bar codes or take photos for storage and quick access later, either via your mobile or the Web. It's very user friendly and visually appealing. For example, I just saved a YouTube bookmark for HBO's Flight of the Conchords comedy with the label "Must watch more." In fact, I feel like I should be using this Swiss Army Knife of tools for more, but I know I will find a way -- over time -- to reach critical mass. I'm not worried, though. Unlike the saved receipts, stamps and other bulk from my actual wallet -- now lying in a pile of papers on my desk -- Springpad's pile is sortable by date and searchable. -- Mike Barton
