Ya, and when you think that most written reviews on the Walkmans were with early firmware? That’s the thing, who knew that they could continue to figure out how to make the players sound even better years after their release? It’s amazing! The question is if you gel with 3.01; I do, though a few don’t. Also it was strange how big the jump was from 2.0. The question is.......how will 4.0 be? Also we were wondering that there must have been a BT receiver chip installed always, just sitting there waiting to be activated. Lol It’s all in the realm of computer game Easter Eggs.
