I was watching the Samsung galaxy S6 keynote yesterday and one slide particularly caught my eye.
The speaker was talking about battery life of the phones and showed it using a cool little graphic. But something seemed odd. If 12 hr is represented by top middle dot and 13h and 11 h are at right and left side of 12 respectively then shouldn't 49h dot be at the right side of 12 (since 12*4=48)?
This is what other companies lack. Attention to detail. However minor it may be, attention to detail is Apple's most important element in their design philosophy and I feel it's one of the factors for their enormous success.
