For me its a very nice bedside ebook reader, reddit machine, and video device. Its a perfect size for all those things, perhaps a bit too small for video but good enough. It can fit into a large coat pocket or a medium sized purse too.
I keep trying to get into my kindle but just can't for some reason. E-ink is nice but being able to get a nice glowing black background with white text is really nice and the page changes are so much more fluid than e-ink.
Way more distractions on an iPad, though.
