Okay, this is bizarre and perhaps it has something to do with my microSD card install. Everything has been working great until now. I used the Focus heavily all morning. Browsing the web, installing apps from Marketplace, syncing music via Zune, Twitter, Facebook, etc. I get an alert that my battery is low. Prior to powering it up, I wanted to check the browsers user agent, so I sent off a link to my Focus. Well, I pick up my Focus and all the information is gone. No music, no accounts, no apps that had been downloaded. Battery is critically low, but everything is gonzo. Has anyone had this happen to them? Did you have a stock Focus or did you have a memory card installed. Going to charge it and see what happens.
