I've used Evernote for a while to keep records of meetings and plans. But is a worthy, free competitor that brings some cool new tricks to notetaking. For instance, you can import a recipe from a cooking site, and Springpad will automatically parse out the ingredients you need. Click a link, and it will add those ingredients to a shopping list. Type in the name of a movie, and not only will the service add a note with a description and image, but it will give you local showtimes or add it to your Netflix queue. A companion iPhone app lets you add and access notes on the go. You can even add a product by scanning its barcode with your iPhone's camera.

Even if your business trip goes off without a hitch, you'll have to deal with all those receipts afterward. And who can remember a week afterward what the taxi ride cost or why the bottle of single-malt scotch seemed deductible? With , you can keep track of your expenses in real time, using any PC or phone. You can add an expense through the free service's site, by e-mail, IM, text message, or voice call. You can even keep track of your costs by sending direct messages on Twitter. Send in a photo of the receipt to prove that a cheeseburger really can cost $20.
