I'm surprised by how much the whole space grey v silver issue has been on my mind since buying a 14 in space grey a few weeks ago.
I usually go with SG, so I didn't think much about it (and after several MBPs in space grey, I've not had any chipping or fading). But since purchasing the 14, I keep seeing silver models out and about or on YouTube and thinking damn that looks good!
I think the earlier poster, Patcel, put their finger on it: it may have something to do with the design being a throwback to the earlier Titanium G4 design, which was a combo of silver and white.
Either way, it's harder than ever to decide on color. I love my 14 in space grey. But now I'm constantly second guessing my choice.
