Hi Graham, sorry for joining late to your thread.
I bought my BeoSound 2 in early 2004 and still use it almost everyday. I have also bought and used iPods and Creative MP3 players during this time, which at the end of the day have just not been to my liking.
No MP3 player beats the design of the BeoSound 2 in my opinion and the build quality is equally as good. I also rip my music from CD at a high bit rate, and the sound is also better than any other MP3 player I have used.
In terms of memory, it is not as impressive as the iPods and using a 2GB SD card becomes a bit clumsy to find the album or playlist you're after sometimes.
I use a 1GB card which is easier to navigate and will hold more than enough music that I'll want to have on-the-go for a week or two.
Having no screen isn't such an issue for me, as I update the music on my SD card regularly and I'm happy for each track to play and lead on to the next. No screen also means a much better battery life 
BeoPlayer takes a few go's to get used to, but after that it is equally as simple in its function as the BeoSound 2.
If your friend initially wanted a BeoSound 2, then I think she should get one and will like it.
PS. I bought a BeoSound 6, but for me it hasn't beaten my BeoSound 2.
