Why argue points I've already stated, yes you don't get 3G access everywhere, and yes there is a limit to non-Amazon files or personal docs (and I do have over 3gb of space on my Kindle as I don't own a paperwhite

).
The bottom line is, both the Kobo and the Kindle have 2GB internal storage, and both are expandable, one with a physical SD card, the other with cloud based storage. Obviously the SD card is a better, more versatile option, but it doesn't mean the other is non-existent, that's the only point I am trying to make.
