Well I have over 2000 units in the field with T26, running 16MHz with 5V 
psu, and not one is flaky, but then I know my supply is rock steady, the 
boards are in an EMC enclosure and all external wiring is well protected 
(by RC networks when they hit the inside of the enclosure).

I am yet to have a flaky product with ATMEL parts (except when I stuff 
up and forget to program things like the BOD enable fuse ;)
