Because my lappy won't fit in my pocket
Because my lappy doesn't go two weeks without charging
Because my lappy can't be read in the sun
Because my lappy is difficult to read in bed/bath
Because my lappy cost £399 without free 3G
Must hundreds of other reasons.

Ahh but my Kindle app is on my pocket sized Android phone. I am sure a kindle is great, but if it was just a book reader i wouldn't even consider one.
