Unless we are being sarcastic, its perfectly normal for a device with limited storage and restoration capabilities to have an image for restoring the device. Its an enterprise device and if IT people don't find the need for a bootable image that you remove immediately you are done, I can imagine the average user. That image gives way to bigger and potentially bigger storage when you add SD. iOS devices don't have that capability at the moment.

That said, unless we are being sarcastic, I find the quality on the list to have deteriorated severely to the level of hawking merchandise and making fun. Im on the list to gain and disseminate knowledge but on a number of times I've had to quarrel on the level of engagement on the list.
