I'm definitely a backpack person. The blue backpack that came with the laptop looks just like my real Jansport backpack. I have 2 of the messenger bags so 2 dolls can use both versions(got on sale).

The new one which I just got looks like a real backpack and you can easily put more stuff in there besides the 2 books it comes with. I like to put mini marble comp. books I get at Walgreens in everyone's schoolbags as well as a mini AG book that comes with the mini dolls(book report?).

Anyways, I could easily put all 4 of those things in the new backpack and the blue backpack, but I can only fit a couple of things in the messenger bags. Plus the cell phone case is removable and can be put inside the bag or around the strap.
