I'm fairly new to eBookwise and still getting the hang of getting stuff on to the reader. The biggest frustration at times is just finding books that I want to buy. Normally I choose books by either browsing at a bookstore(or at amazon reading reviews and the "also bought" links), or just going with an author I know and like. EBookwise.com and the other sites I've checked out haven't had great browsing function.
Now I'm just curious how other owners of this device find there books and get them onto the machine.
So to the point of this thread:
What do you use this for?
Where do you find content?(What sites do you go to)
How do you get content on to EBookwise?
And Why? - both why for both the how and where sections.
