We're not entirely sure what we'd do with 10,000 iPhones. Even if you just used a different one every day, you'd still have enough iPhones for more than 27 years.
That said, this video by CG animation studio Aatma doesn't, in fact, feature real iPhone 5s. The phones are actually very clever CG, which is unsurprising, coming from Aatma. The studio has created a plethora of extraordinarily realistic iPhone "concept" videos.
This particular video was created as a "mock-up" of what an advertisement showcasing the iPhone's NFC feature (which it doesn't have yet) might look like.
