Thanks. The backpack-bag is no longer an issue. The rubberized case is.
Also, I would like to get something between the keyboard and my fingers as I don't like nor can't get used to how uncomfortable typing on it feels. And it's worse ven than you think. The layout (Spanish) comes with that deleterious "intro" key, so there is a lack of choices when it comes to whatever could make typing on it a pleasant experience.
