Here is what I have gathered:
Both units have similar sound quality. As a result, purchase should be decided on features:
MuVo N200 Features..
- backlit display
- preset & user definable EQ settings
- ability to record 96, 128 and 160kbps MP3s (line in)
- ability to record voice using built-in voice mic
- ability to listen to FM radio (and record it)
- USB Mass Storage support (drag and drop)
- Use of easy to find AAA batteries (as well as ability to use with low cost, rechargable NiHM AAA batteries)
Shuffle Features..
- full size USB 2.0 connector -- no need for cable
- smaller physical size
As an owner of the N200, I have found the following..
- backlight hum is slightly annoying .. though most of the time, the backlight is not on (during play) and the player is VERY quiet which is nice (almost too quiet). The backlight can be disabled -- ipod shuffle doesn't have this issue (no display)
- Use of AAA batteries is nice.. I had recharagable AAA batteries from my old PDA which work great in the N200.
- USB 2.0 transfers are very fast .. I am unsure how this compares to the Shuffle..
- Controls and interface is straight forward. I was able to navigate and find my way around the unit with ease.
- Ability to record with the line-in is awesome (main reason for my purchase) -- I have recorded from a huge array of audio sources direct to MP3 and its great.
I ended up getting the 256MB MuVo.. I intend to use it as an ultra-portable recording device (band practices, live performance review, etc..) and 4hr recording at a time is more than adaquate. If your looking at price, the 512MB Shuffle is $99 compared to around $119 or so for the 512MB MuVo.. I think it ultimately depends on you if the additional features are worth it.
Now if I could just find a nice powered microphone that I can connect direct to the line-in on the MuVo, I'll be set.
