I also have more than one chef's knife, more than one pair of walking shoes, more than one hair dryer, more than one crock pot...
I don't understand the question.
I have an Oasis 2, Kobo Glo HD, 2 iPad minis, 1 iPad Pro, 1 iPhone 7+, and various devices not currently being used. The ones I mentioned are all in use, although the Kobo not too much right now.
