Hey, I like biabia’s concept. It might just be a messenger bag, but being able to hang it on your chair is something that appeals to my inner OCD (cleanliness, not touching the dirty ground…).
Hs.wang’s concept also interesting. Personally not something I’d wear around, but cool looking anyways. Though I’d hope that the pouches are fairly secure, as a tug from a slightly annoying friend or very annoying enemy/rival-type could possibly rip them off. Which I’m assuming is a bad thing…
marker’s briefcase/satchel concept looks nice. But one question: Is the material hard or soft? Because if it’s soft, then the A3 marker pad/book container could get pulled up and bend the pad and books. Maybe you already thought of that, but just thought I’d ask…
[Note: If anything I said SEEMS like bashing, it’s not intended that way. I know I’m a noob, but I am merely trying to give suggestions so that if they consider actually constructing a prototype, or whatever, they’ll have some feedback.]
