The biggest thing is the battery. The CPU doesnt get too cold, but batteries degrade or stop performing when they get too cold.
Edit: For actual temperatures, in my experience its when the device is in use for a sustained amount of time in under 10f weather
Incidentally CPUs do get too cold, not at a reasonable temperature, but sufficiently low temperatures do change the characteristics of semi conductors. Not something to worry about if you're not using liquid nitrogen (or colder).
