I've been thinking about how it's perfectly possible that, over the following year or two, the MBA family might totally cannibalize the MBP family, just like the MBP 13" recently cannibalized the Macbook White 13". Here are my thoughts: 1) We've seen how MBA 13" can match MBP 13" component-wise (Sandy Bridge i7, HD 3000, 6-hour battery life, etc), so there's no reason as of why a hypothetical MBA 15" and MBA 17" couldn't match a MBP 15" or 17". 2) Hard Drives and DVDs are aging technology, and it won't be long until Apples phase them out completely. So, if they remove HD and DVD from a MBP, we get... a MBA, basically. 3) Marketing and logistics wise, it's counter-productive for a company to have over-lapping products that cannibalize each other's sales. Let's face it: the MBA 13" is a direct competitor to MBP 13" now that both are equipped with the same processor. Apple already ditched the Macbook White for this reason (it overlapped with MBP 13"). So I was wondering: couldn't it be possible (or even beneficial!) that Apple could release sometime in the future a MBA 15" and 17", and get rid of the MBP family altogether? or at least unify them in some way? Now that the performance gap between MBP 13" and MBA 13" is basically non-existent, why not merge them? and why not do the same with the 15" and 17"? I foresee Apple unifying both product ranges into one in a not-so-distant future... Opinions?
