The company hasn't changed in ten years. Their notebooks today look virtually the same as those from ten years ago. Maybe a little thinner, plus they come in different colors, but that's about it.
Apple's Mac Pro looks nothing like any computer ever made before, and their new MacBook Retina machines are radically different from their 2004 Aluminum Powerbook models.
I kind of like HP's redesigns, it shows they're trying. The Envy isn't bad for a MacBook inspired knock-off.
