The CPP isn't really all that bad.
yes, it's a bit bulky, but that just makes the 3ds more comfortable to hold.
Because of this and the fact of there is a second CP and 2 shoulder buttons, I dont mind the "ugly" bit that sticks out. i dont find it that bad.

So, if you dont like the CPP, you dont like it, its your opinion. No one is forcing you to buy it.
