oops! I just read it again... it is the exact brand I bought, but this is the previous model: E-2000, 1 Gig memory, and the one I bought at
http://bigreach.ca is the newer E-2003 2Gig model. I think you can do an upgrade on the E-2000 model to bring it up to E-2003 in function, but it seems to have half the menu. The Disney books are available on Amazon.com as well I think, for the eReadbook pen.
Note that this is a battery powered toy thread, and this does NOT take batteries: it is rechargeable with any regular electrical wall socket.
