I disagree with this. e-Books offer a superior reading experience in almost every way except "if you fall asleep while reading and the book falls, you don't break your nose or damage your book" (which regrettably has almost happened to me on several occasions).
There have been several books that I willingly paid a higher price for on the Kindle as opposed to getting the paperback at a book store.
The convenience of having all your books on a single slim device (or synced between two) and not taking up physical space in your house is great enough for me to pay an extra Rs100 or so.
That said, I agree with the point on the whole - most people don't think like I do and will expect the ebook to be cheaper and will feel completely ripped off if it's not.
