Apple have created a mess by providing multiple options between Airs and Pros. If you upgrade the RAM to 16GB on Air it surpasses the base model of Pro and similarly other storage options. At that point you should rather buy a Pro over Air because the only major difference is size. Lot of this is totally confusing for non-technical folks and they might just end-up making a wrong purchase.
I completely agree. I've been using MacBook Air mid 2013 for the last 5 years and it's a great laptop. Now I'm considering buying a new one, and Airs just don't make sense for me anymore. In Singapore the difference in price between cheapest Air and cheapest Pro is less than SG$100 (US$70). The only advantage of Air is longer battery life, but that's it. I think at this point the Air series should be merged with MacB…
And less weight.
(I was going to say "and less volume", but one end of the Air is actually thicker than the MBP, so overall volume might not be that different in the end - even though it does look smaller.)
