A new mobile device doubt

[nradam]

Suppose i am making a new mobile device like a new ebook reader. I want to use android, but i would like you guys to tell me whether a device with the following criterion is possible:

a ) I want my reader to directly go to the application for reading books as i start the device. I dont want a desktop, icons etc.
b ) I only want my reader to read pdf and not play songs, videos etc. Infact, it wont even have a speaker.
c ) I want to start-from-scratch develop most of the device, even the motherboard.


The above might sound corny to some of you, but i would be deeply honored if u answer

Sure that's possible. It's a one-trick-pony. Just flash some eeprom. But how about other components like I/O, storage, connections, etc.? And what would the end result look and be like? Why would people want it? Would it be affordable?
