Let me start by saying that I think the current MBA design is great and beautiful. I'm not saying that I'm demanding a redesign, or that I even have a single CLUE as to what Apple could do with a redesign.... but its inevitible that every single device either becomes discontinued or is redesigned. If you look at the history of Product redesigns (iMac, MBP, and even MBA), the average time to redesign is about 2.5 years. The current MBA is just over two years old. In fact the only product (that I have found) that took longer than 3 years to redesign is the 4 years it took for the unibody MBP (mid 2008) to update to retina (mid 2012). I understand this is all just speculation, but don't let that stop you! And while we're speculating, what do you think Apple could even do with a MBA redesign?
