AT techies or anyone else who wants to take a potshot:  (explain this)

Why exactly is this a useful project that people want to fund on kickstarter?  http://www.kickstarter.com/projects/125911486/cloudftp-wirelessly-share-any-usb-storage-with-ipa?ref=card

I found a few off the market brands from seagate and other well placed branded mfgs making these since 2011.  External USB ipad storage, I would imagine is nothing new.  So why exactly is this project getting funded.  All I can think of is just novelty but it doesn't make sense to me.
