A Food Dehydrator

Back on the dehydrating trail again, this time with some bramleys from alottment...............and thereby lies a problem with the gadget as it stuggles with large or mishapen apples.
I like to get some use out of the dehydrator mainly for drying various meats so this fruit drying is new to me? What do I use the dried eating and cooking apples for and do I dry them until they are like crisps or do I keep them slightly leathery?

I still have quite a few of my sweet apples still on the trees so wondered whether to chop and freeze or chop and dry? Apple chutney sounds nice too!
