New Beta firmware 2.x works fine on my Zen MicroI have downloaded the new beta firmware and tried out for almost a week now. So far so good. Haven't encountered any problem yet.
For those who have problem in connecting and synchronzing your Zen Micro with PC, this firmware worths a try. Before upgrade, I always have trouble in connecting my Zen to my PC. The Zen hung in the middle of some where. The only way I can get the two pieces working together is to (1) remove the battery first (2) connect the two pieces with USB cable (3) start WMP or Zen Explorer (4) put back the battery. It is very troublesome. I have tried different firmware version; all failed to establish a reliable connection. Now the new firmware seems to get rid of this problem. Sychronization is very smooth after firmware upgrade.
For those who are using original 1.x firmware, music transfer via WMP10 is as slow as USB 1.1. In 2.x and the new beta firmware, song synchronization is significantly faster, gives me a sense of USB2.0 speed.
BTW, I think the new firmware adds a ICON on the Radio screen to show radio signal strength, like your cell phone. Good to see such little thing added.
