We use voice recorders predominately for travel, and previously (well, post-cassette era anyway) had an Olympus unit. The Phillips unit here Philips LFH0655/27 4 GB Rechargeable Digital Voice Tracer with ClearVoice and Stereo Recording is slightly larger than the Olympus, but seems easier to use. In addition, it records in both MP3 and PCM ("wav") formats whereas the Olympus was WMA only. Recording quality is excellent, as is recording capacity - the specifications list days rather than minutes or hours! We cannot speak to durability yet as we haven't taken the unit on the road, but general impressions are that, with decent precautions, longevity shouldn't be an issue. The ability to charge the internal AAA NiMH battery via USB is a nice touch, as is the ability to use a standard alkaline battery if needed.
