Listen, your digital voice recorder and your smartphone don't have to be enemies. Take the DM-901 from Olympus, for example. The new model extends an olive branch in the great voice recorder/phone wars with built-in WiFi, which lets it communicate with the Olympus Audio Controller app on your handset, so you can upload files to a Dropbox, tag them with images and links and share them with other devices. The 901 has a 2-inch color display, a zoom mic for longer-distance recording, noise cancellation and 4GB of built-in memory. It's dropping next month for $200.
