The same could be said for the iPod and the Zune for example. Yet these devices are used by average users every day.
Portable audio players became mass market without any major store offering a large collection of songs. Even iTunes had a rough time building a decent collection.
Although DRM-less files, multiple stores and a very large number of e-books available would be heaven, the music industry already proved that you can reach mass-market appeal without all of this.
