The weight difference between Aluminium and Steel was/is very noticeable, in the hand as well as on the wrist. The difference between Titanium and Steel will be almost exactly half as noticeable. So, a nice middle ground between the heft and premium feel of the Steel and the airyness of the Aluminium. Also, saphire crystal glass and 2 years warranty (3 with Apple Care). Sounds like a winner to me.
