Day 4, no scratches on my SBTi. Still undecided on if I am keeping it when my ceramic arrives. I love the matte black finish in indirect lightning, but it gets a bit too bright for my taste in direct sunlight, like while driving. I really wish that had just made it a straight flat/matte black. I think of the two titanium finishes the silver is a better look but less hardy.
Tough call this generation! I really wish Apple had remade the grey ceramic, then it would be a no brainer, I miss my old series 3.
