I actually like the new Tropicana packaging (as shown at the top of the article). It looks more hip and healthy, like something that would be sold at Whole Foods, as opposed to the old packaging, which strikes me as more nostalgic (e.g. "Your Father's Orange Juice").
I'd have to agree with you there. It reminded me of some freshness and they did some good for the packaging, in my opinion. I might just go out and get a carton myself, for posterity, since they're discontinuing it.
It kinda reminds me of how when facebook changes its interface, people bitch and moan, for about a month, and then, they kinda just forget what it was like before.
This thing with tropicana just sounds like people resisting change, for tradition's sake, rather than evaluating the new thing on its own merits.
