Well as a younger traveler, I can say there's no way this service can let me pack nothing (well espesically since it seems we still need to pack underwear) since I'm probably going to be packing a laptop/tablet and such. What this seems to be right now is just a pack less service... which just doesn't seem to attractive, I'm sure for frequent travellers we have packing down to the point where its not much of an issue, personally I have travel essentials basically prepacked at any time so I just need to go into my closet, pick up a bag in the back and I'm ready for a 3 day trip.
Now, if you are offering really nice or niche stuff (since this service basically seems like renting clothes at your destination, like a rental car in a way) then I could see myself using it.
