Between me and my husband we've owned more MP3 players over the years than I can count, including Sansas, iRivers, iPods (classic &amp; touch), the Ibiza Rhapsody, etc. But, the last few years I've settled down to one line of players. Why? Because I was happy to discover how well-designed and fun to use the underappreciated (and widely mocked) Zunes are.
