The entry level 13" rMBP is the same price as the entry level rMB. Yes it's heavier than the MBA but I'm guessing people that need more ports and power are less concerned about weight. It seems to me Apple's ultimate goal is to phase out the MBA when they're able to make the rMBP thinner and lighter. So then they'll be down to two laptop lines: rMBP for people who need more ports and power and rMB for everyone else. Is it possible that the rMBP could become thinner and lighter with Skylake?
