Why would anyone want their screen to be anything other than a featureless rectangle?
There's a huge market for making TVs look like anything other than a slab of glass. Aesthetics count. Is why the 17 inch iMac with the crane neck is still covered.
For what it's worth I don't think featureless rectangles are a bad thing. I'm just saying that it gets hard to distinguish products from each other when the designs converge so much.
