I called my mom today and asked her why I didn't get a pouch, it would have been so cool...
She said that the blueprints she had for me and my brother came from the Advanced People Emporium (APE), a very respectable but slightly conservative organization that does not like uncalled-for bells and whistles such as the pouch (or the tail, come to mention it). All their current products are market-proven and have successfully undergone extremely long tests that guarantee robustness and long life expectancy.
There was, in fact, a competing organization, the General Operative Development (GOD) that promised a much faster time-to-market for new products (even six days for whole universes) and was known to be much less constrained in adding new features, but she did not trust it very much: first of all, she could not find a phone number for the main offices, and although all the different outlets she found claimed to have exclusivity, yet they were inconsistent in their messages and very aggressive in their marketing. And second, she did not trust the material for the product, since blown dirt seemed to her a little fragile, and she was afraid it could get runny in rainy weather.
Maybe you could tell us your experience.
