My personal opinion.
I always had my MP3 player in Shuffle Repeat mode, so I think it is nothing wrong for iPod Shuffle. Of coz I am not that stupid to think Shuffle mode is invented by Apple.
While I impressed with the iPod Shuffle ID, I prefer MuVo N200 better, for a couple of reason.
1. Battery.
I prefer the idea of removable battery and the idea of using AA or AAA battery. Reason is simple enough, when the battery run flat, what I need to do is get a new battery and slip into. Battery pack just make the player looks bulky. Plus, there are lots of Rechargable AA or AAA Battery selling out there and I bet they are much cheaper than the battery pack in term of playback_time per dollar. For me, Apple just want to make more money from its accessories.
2. LCD Screen.
A LCD screen is handy for me. There is time when I was in mood wanted to listen to certain songs, so I scrolled and search the song. That will be a pain if there is no LCD screen. And when the battery is nearly flat out, I can read that info from the LCD screen. If the player suddenly stop, from the LCD screen I can know if the player is Hang or run out of battery. Honestly, lots of benefits with a LCD screen here.
Plus, with its size, if there is a FM Tuner will be better. But this is subjective.
