Thank you for your wonderfully ground breaking insight.

but having worked in marketing and advertising for most of my career I will have to disagree with your intial comment.
Obviously every product line has a cyclical refresh. We all know consumers can become tired and the competition will always be snapping at your heels. Hence my comment on the "competition is killing you".
The point I was merely trying to make was that I'm still happy with the aesthetics of the latest MBP and that a drastic change in form factor should, and will be down to technological advances. I'm all for that. But I'm not that keen on the MacBook Air.
Marketing and design go pretty much hand in hand my friend.
Whilst Senior Designer for Sony I had to regularly work with over 20 European marketing managers, who were constantly wanting point of difference from product, packaging and comms.
Im a graphic designer who was responsible for most of Sony's european branding and packaging offerings for 4 years and like to think having worked in packaging for years, winning awards too, I know enough to make my personal comments here. My two penneth anyway.
Just my response mate. I'll be buying the new MBP whatever it looks like. ;-)
