Q: on ipad how much storage is used by the operating system and apps

About 2GB. Why do you ask?

 Cheers, Tom

About 5 gbs on an iPad is used by the undeletable apps that apple has created, but these are included in the listed storage, so a 16 gb ipad actually only has about 11, a 32 has about 27, and so on.

5GB is not correct.

There are several factors that affect the amount of storage space on an iPad. First is the true amount of space on a hard drive. There is a math difference in how companies spec hard drive size and the true amount of available space. Second the iPad has some pre-installed apps that take up space. My 16GB iPad 2 started out with only 13.5GB of available space.
