The new logo has been rolled out on March 8, 2011 to mark Starbucks' 40th anniversary. What a nice way to celebrate, huh? ;-)
Actually, it's been months since I first heard about this change but I never really paid much attention until yesterday (6 days after! where have I been?! darn!) when I got my cup of cappuccino that I noticed the new look of the Siren without the words "Starbucks Coffee" around it. Personally, it lacks the appeal of its predecessor and looks weak. If they want to symbolize "freedom" and "flexibility" to think beyond coffee, I guess the new logo failed to project that image. Oh well, this is just my 2 cents worth of opinion and I hope I was wrong.
Anyway, they say life begins at 40. With that said, here's to a good "start", may you be more inspired for the next 40 years... and beyond! :-)
