Over the last two weeks of ownership, I have noticed a substantial drop in carrying weight. I thought 1 pound wouldn't be noticeable, but it was. In fact, I constantly checked my bag to make sure I didn't leave the computer on my desk at home... or on a random table elsewhere. I could not perceive the device at all. It was like it wasn't even in my bag at times. The screen is nice, and so is the performance. But I think the weight and slim profile of the rMBP take the cake. Anyone with me?
