That's not been my experience. Having an alarm go off in a PalmOS app causing the VM to not only crash, but become corrupted is not my definition of a "stable environment."

Not that it doesn't work for some apps. I've successfully run some of my old Palm games in it without problem - until the VM corrupts itself and needs to be restored.

That's why I say to not rely on the VM for anything important. The VM can corrupt itself, rendering it useless until you get it restored.
