I almost bought one today but I looked at the find print and there is no sd card slot, so you can not add memory. I am out on this product. I think it is dumb that they decided not to offer a sd card slot. My Android phone has 8 gigs on-board and I have a 32 gig sd card installed. All the memory is almost filled, so I can not imagine how the Nexus 7 would work for me with even the 16 gig version. I have a lot of book, some music, and some pictures and a lot of apps installed but not overly loaded with junk, just what I need to get by. I am going to wait and see what comes out from Amazon and Asus in the next few weeks. I am sorry to see the Google Nexus 7 come out with this package.
