I still have an F20 floating around here
I always liked it, because it was about the size of an old text radio pager i once had, and did indeed make a neat one-album player.
I'd love to see a modern hi-capacity come out similar to to.. as a budget player-only device.
Would then leave the Perstel Chic MP10 for dead on looks and robustness :P
For ref - until very recently, Chic Mp10 was the budget priced mp3 deck obtainable over the counter.
