Just reviewed by CNET:
It should do everything you want.
As far as music services are concerned, the only thing you can do is try. I don't have any experience with that genre of music. I would advise against iTunes unless you have an iPod. While you can put purchased music on any non-iPod player that supports AAC (the Samsung P3 is one of them) without conversion, it is a resource hog and you wouldn't be able to transfer music within the application to any non-iPod. Try Amazon.com's mp3 downloads store first, then perhaps Rhapsody or Naptster's stores.
I am a complete newbie when it comes to MP3 players.
Here is what I think I would use one for:
1. play audio books from public library (these would be on CD's)
2. play music from my old CD collection
3. display photos (.jpg) from my Canon SD800IS digital campera
4. display video clips (.avi) from my Canon SD800IS digital camera
Note: Most of the music is like is "old time classic country". Stuff that was recorded 30+ years ago. What is the likelyhood that some of this music can be downloaded from I-tunes and sites like that? Or do they just have the current music?
Will all mp3 players do the 4 above tasks? Is it simple to load the audio & video files?
In addition to your answers, I would like suggestions as to what player I should get.
