If you caught a glimpse of last night's American Inventor, you know good ideas are few and far between. To ensure your great ones aren't lost, you might want to invest in a voice recorder like IBM's planned Magic Block. Designed to serve as a private digital sound diary, it can record nonstop for an entire day (IBM is mum about how many megabytes are actually onboard, but you can assume it's enough to keep up with your brilliance). To manage your recordings, a search function lets you look for clips by uttering a keyword, typing in a time range, or looking for a specific person's voice — voice-recognition software allows names to be linked with voices. If you're worried about opportunists stealing all your great ideas, an embedded fingerprint reader secures data privacy. No release date or price yet. — Trevor Noren
