Hi I have a vision M for about 3 months now and so far is the best thing I have ever brought. It plays pretty much everything u chuck at it except real and quicktime files, which is the only let down. Some video files needs converting but the software does that for you anyway. The built in FM radios reception is better than my own amp, and gives u that little extra when the battery is low. I advise you get a leather case or plastic skin to protect it and DO NOT remove the plastic film on the screen as you will regret it. MP3 playback is 10/10 and is easy to use. The touch pad takes some getting used to but u do after time. Th ebattery life is around 13hrs on mp3 and around 4hrs on video which is ample for a film. I would hunt around for prices thow last time I check PC world had it for £189 and about the same for Amazon, the case is available on Amazon as well.
Hope this helps , any other questions just ask or pm me.
Regards Pete
