I don't want to jynx it, but I am surprised at how long it's been since my last reset.
With previous models of palm pilots, resetting has always been a thing to deal with. I would say, the most stable PDA I had was the NX60, and I still had soft resets happen every couple of hours of use. and warm resets be needed every so often.
I really cannot remember the last time I reset my treo, but I think it was after installing some app that only ativated after a warm reset.
I hesitated buying a treo for six months, because of all the horror stories of constant resets. esp when receiving calls.

I am so stoaked [knock on wood!]
