Ok, I am RMAing my 860 to Dynamism. I'm getting the Blinking Mail-Light of Doom that has been reported by several other posters. You know the issue: Suddenly Zaurus starts locking up repeatedly. Can't do a soft reboot. Hard reboots inexplicably fail. Then, you insert battery and get a blinking Mail/Recharge Light. My question: Is this a common problem? Are there any known causes? I'm hoping maybe somebody with Trisoft (Marc?) or Shirtpocket or Conics has some statistics. That might determine whether or not I keep the Zaurus when/if I get it back. Thing is, I really like(d) my Zaurus. It had the longest battery-life of all the PDAs I ever owned. I'm back to using my Sony, and the battery's a third-gone after checking appointments a few times. But I can't have something that's in for repairs all the time. So may be getting one of those new Palm Tungsten Xs when they hit the shelves in May. (Bigger battery than Sony and built-in Microdrive, like C3000). I'd really like to keep it. Thanks to Anton Maslovsky and the Cacko Team, I was starting to enjoy it more than the Sony, and that had been my favorite. If there is something I was doing that caused it to croak, I'd gladly stop, but I'm afraid the answer is that it's a random quality issue.
