I don't think it's really fair to come to the conclusion that Windows Mobile itself is quirky and subject to lots of resets vs OSX mobile when you're comparing it to a hardware platform with double the memory (not to mention the processor speed, optimized apps, limited operating environment, etc). I only had to reboot the iPhone once in my 2 week period, but Safari/iPod functions do crash alot more then they should in such a sandboxed environment. I will say that a quiet crash is much more acceptable then a hang.

I would love to get my hands on a Kaiser or Athena/Amero and then come to some conclusion based on a more level field hardware-wise.
