Shoot, I was gonna say that about the roomba BigJim, but you beat me to the punch, oh well. As for those mock-ups they do look kinda cool, but I dont like the controller and Ninty really needs to come up with something really unique, not so much that it is rediculous, but unique. There is an advantage to side loading systems, you can stack stuff on top of them to save space, the top loading system on the GC effectively makes it a few inches taller, and the shelf under my tv is crowded anyway.
