The straw in orange is also a fun and friendly image, without going overboard. It invites people to "solve" the visual equation. Straw + orange = fresh juice. A clever design for young and old. Amazing they replaced it with a boring glass of OJ.

Replacing the horizontal convex "Tropicana" with the straight vertical and using a more serious font, was another blunder.

They probably just got lost in many design reviews. At the end they couln't "see" the designs anymore. Also their test group was probably biased: They probably used the same guys to review all design iterations, so their opinion developed along with each iteration.
