I currently own Macbook Air i5 2015 version and its being a bit slow for the task I'm doing, I'm a heavy chrome,phothoshop user and rely on gmail and extensions so 8gb ram is too little as is 128gb ssd. I was planning on buying the 2017 pro with 16gb ram and 256gb ssd but I've read somewhere that quad core version of coffelake is rumored to be released next year, I assume it will only be faster in multicore situations if true. I don't do much video edit but I might at some point. What do you guys think, should I go for this years model or wait and see what next one is up to?
