Why don't consoles offer mouse input?

[BD2003]

If it was only that simple. They need to design the devices, create them, test them, make sure they work and meet certain standards, then start advertising - this costs a LOT of money. If only a very limited amount of people would buy that (and this is also what I think), they wouldn't even get a return on the costs of putting the product on the market, let alone start making profits...

I know.

I just reject that profit is the motive here.
