I am still astonished that people still make power supplies with those huge bricks that plug in. It's such a burden when you want to plug in more than one thing. The power supplies that come with the Empegs are nice, but I still don't understand why more electronics companies don't make mid-line wall warts, you know, the type where the brick is in the middle of the power cord so the actual plug is normal size. I've got an effects processor that has this, and it's just so convenient.

So my question for the more electronic savvy people here: Why aren't more of these mid-line wall warts made? Too expensive? Some weird burden on the power running through it? It just seems too logical to use these versus the big brick style plugs...
