For those who think that there is no market for such a device, just put yourself in the place of someone who dosen't know anything about computers. Those people have three choices and all of them have drawbacks.

1) use a browser/computer wallet  = computer could get hacked.
2)use an smartphone wallet = smartphone could break, possible malwhare, accidently deleting app (i have seen it a lot)
3)use tresor = a noob would and understand and you would have to connect it to a computer to get it working.

however a true single purpose hardware wallet that coulse wirelessly theter to a computer to get internet connection would not have any of those problems and also you could just give them to friends, family.
