Summary: I work on a community newspaper and we use these and the earlier ICDSX57 (identical except 256 MB) for recording the meetings we cover. The unit is very portable. The recording quality is excellent even in rooms with poor acoustics. I keep mine set to the highest quality setting and it will still record about 9 hours of conversation. Note that if you put in rechargeable batteries, they'll be recharged through the USB connection. That's very handy.
Summary: I love the portability of this little recorder, its computer compatibility and recording quality (near CD quality). That said, if it could be CD or better than CD quality, it'd be even better. I bought it because I am a singer/songwriter and music lover who needed a reliable, portable device to record my songs, ideas, etc. For its cost and what it can do, it's a real bargain.
Summary: Although this was described as a "Flash Recorder" it in essence is a Digital Recorder with mp3 capabilities. This is a slim, lite weight recorder with great features and the quality of recordings are excellent. I work in radio and use my recorder to do interviews for news and sports. My only complaint is that they don't tell you in the manual (or at least I couldn't find it) how to how to convert the files to mp3 on a different editor (Adobe Audition 1.5) Once I figured...
Summary: The features are top notch and the look is fancy. I love the silver look and the quality. This is the best recorder I have found. The software makes storage and files easy- no problems with it. The recordings come in perfect and clear. I feel I have a professional recording studio on hand. The storage capacity is all I will ever need. The design is beautiful. I like the silver buttons on the side.
Summary: Product does everything we want it to do, and that very simply. Software manages filing and editing. One downside for us is the fact that the that the documentation said something which led us to believe that the recorder has an input plug for an external power supply. It does not. We have found it cost effective and handy to plug into an external source because (1) it saves buying batteries; (2)every presentation is recorded week in, week out.
Summary: Just is great. I got it for Christmas to use for making mental notes and voice general recording. It looks overwhelming at first, the buttons can be difficult to learn for some -- but I'd imagine for most people it's relatively easy to navigate its. The sound quality is superb nothing less than you would expect from Sony.
