When e-books concept came in, at that time everybody thought that paperless office culture will come very soon, but later it proved that now e-books are coming in paperbooks format!
e-books
are useful for transportation only. People then take printout of that books. This happens in very office. Nowdays every company makes profile in pdf format so that customers can take printouts of thir profiles.
Now e-book and paper books are coming one level. Reading on computer is not that much comfortable than on paper.
This is really good idea that reading on palmtop type device but its too much expensive, if there will be any inexpensive solutions our way then people will definitely like to read on palm type devices, bcos reading on lcd type screen is not also easy.
In paperbook case trasportation is the biggest problem, its very much expensive too.
