I took a look at the Q&A. It appears to be answered by users and not 
Apple staff. I also found it contains wrong information (there's one 
Q&A saying the Apple Remote would work with the Mac Pro - which is 
incorrect, the Mac Pro lacks the necessary IR receiver). So I'd take 
answers from this Q&A with a big grain of salt - especially since I 
haven't heard of any aluminium Apple Remote having been spotted in the 
wild.

I, too, have purchased an aluminium Apple Remote and await delivery in 
what Apple says will be a couple of weeks. If you receive yours next 
week already, your feedback and experience with the new model would be 
greatly appreciated.

Best regards,
