Designing the Look of the 360
Gamasutra has a piece up where they talk to the folks that designed the look of the Xbox 360. From the article: "We are responsible for the whole look and feel, the outward aesthetic. This includes the features, how it looks as overall design language, how it works with the controller and peripherals - working on the camera, the charging systems for wireless remotes - and then the box itself, obviously."
"And then there's the Revolution, or Mini - PS2. Maybe it's an improvement in design, and certainly the least painful to gaze upon, but it really looks like a smaller PS2. Is Nintendo trying to confuse people into buying it?"
It's definitely not a mini PS2. It doesn't have those Atari 2600-esque black... spiky things. I don't even know what you call those things, but I've only ever seen them on 80s electronics, certain audio equipment, and the PS2.
I think the rationale for the Revs design was that Nintendo tried to make a console with its own style this gen, and it ended up biting them in the tail. The Revolution's minimalist style is hardly intrusive, but it has its own defining features. It could basically fit with any entertainment center, which is the goal in the design of the casing, I would think.
