MacBook Pro Retina different material from Air?

[crisito]

My MBPr has got a few chips out of the aluminium already. But I had a MacBook Air previously for over 2 years and it never got any chips or scratches at all. I haven't used the MBPr any differently.

So I was wondering that maybe the material used in the MBPr, or perhaps in all new MacBooks, is weaker or softer than previously used. When I felt the material of an older MacBook Air, it feels slightly more textured, whereas my MBPr feels smoother.

Any thoughts?

Chips in aluminum? Aluminum can scratch, dent, get gouged and dinged, but I did not think aluminum could chip. I thought aluminum to be too soft to chip.

Do you have any pics?

I guess they are dents, rather than chips.

A chip would mean a section of it has fallen off, a dent means the material has shifted its shape or gone inward.
