I don't understand the downvotes here. On a device with 16gb of storage, 2gb or so for another OS that you may or may not be able to get back is significant - especially since things like "usable capacity" are rarely disclosed at the point of sale.

That's exactly why Microsoft doesn't make it easy /easier for dual boot Windows /Linux machines. They want you to have more space available. Isn't that great?
