Developers' Box Club

It sounds like this service belongs in the 80s or 90s. Books? Pens? We don't really need these anymore, and it's not actually environmentally conscious to be manufacturing and mailing these things around. And who doesn't already have enough T-shirts?
These days, it seems like if you were to subscribe to a monthly service, it should be something custom-designed to solve your particular problems, not designed to be helpful for a hypothetical "typical" developer.
This seems far too general to make anyone happy. You may need to specialize a bit more. Is this a box with stuff for web developers, academic types, low-level programmers, etc?
A never ending supply of desk mites that I will have to cycle through or throw away just adds stress, not happiness.
