OK, I just thought another potential use of this kind of device: to be used as a music book for music performing industry/music bans, as well as music lovers.

Advantage of this device:
1. can potentially store endless tunes, so they don't have to carry many different music books for different tunes with them.
2. This is probaly the most important advantage: This kind of device can do "auto flip page" (which I will disscuss more on this soon), so while they can perform music and have their hand busy, this device can auto filp pages for them, and on the traditional music book, they can't, they either have to flip by themselves (which is distractiong), or have a dedicated helper to filp pages for them (waste of manpower).

First of all, I think music books might be stored on the device as pdf. This kind of pdf can be potentially obtained from ways like:
1. provided by the music book publisher,
2. or the user may have it properly scanned from existing paper music books (by camera or scanner).
3. Some software can convert midi/mid file into pdf to be displayed as music book, one such software I know is "Midi Sheet Music".
4. other existing pdf music book bank.

Now I will talk about auto flip page feature. First of all, I think auto filp page feature is nice for even non music book uses. You let user to set how frequent they want to auto flip page. And for auto flip page, display only one page and flip the entire page is probaly not very nice (but a feature could be still essential to have), so I think beyond that, 2 better options should be avaliable:

1. display 2 pages at a time (which means the device is positioned horizontally, one page at left one page at right), and after each set time period, the most earliest page will be flipped. This is probaly nice for reading, but for music pages, I think this is still not the best option, since view 2 pdf pages at a time can make things look small, and music books usually placed infront of a performer from a distance, so for music performing, we need to display bigger looking pages, while support autoflip and grant continous reading, so I also propose a second option, specifically for music performing:

2. Display only one pages at time, but auto flip only half part of the page at a time. So page 1 is displayed, then later, upper part of page 1 will be replaced with upper part of page 2, then lower part of page 1 will be replaced with lower part of page 2, and so on...

Also, another auto flip option useful for musicians, could be let them specify the exact seconds for each page turn: page 1 to 2 (or 1 to 1.5), 30 seconds, page 2 to 3 (or 1.5 to 2 or 2.5 to 3), 40 seconds, etc... and if a possible page turn is not given a set time, then it will go with a default time set.
OR(/and) a given sequence of numbers of seconds, to be used to perform each specific full/half page turns.

So basically thats my thougt so far, and of course, since this idea is kinda new, so I do think marketing effort is required for musicians to be attracted to this kind of feature. (Note helping them to get pdf version of their performing music should be a top priority, and then next will be making them learn how to actually use this device, and it should be user friendly and does not require much learning curve.)
