It still plays music. What else is it supposed to do?
The fundamental problem with software is that it just doesn't wear out. An ancient version of Winamp that played music files a quarter of a century ago still plays those music files. This is the perennial problem of software suppliers -- how to build in wear and tear, or just plain obsolescence, into your product line. The contemporary poster child for this is, of course, Sonus who seem to have figured out how to brick product and yet somehow survive the resulting flak.
Meanwhile I'm still using a couple of Squeezeboxes, a standalone Squeezebox player and a service as the primary in-house streaming devices. Logitech did a great job with this range, too good a job (they had a rather neat rack mounted player for legacy hifi systems -- unobtainable, of course) so they tried first to sell a one way 'UE' upgrade which tied the players to their web ecosystem. This didn't work so I presume they're just waiting for the equipment to fall apart from old age. I'm left a bit puzzled as to the amount of effort that vendors will go to in order to ensure that their equipment doesn't "just work".
PS -- Still have, and occasionally use, an older Winamp. Seems to work just fine.
PPS -- Guess who doesn't own, and has no plans to acquire, any Sonus kit?
