In the refurbished store in HK we have MacBook Air 2018 1.6ghz upgraded to 16 Ram and 258 SSD and Pro of 2017 with 3.1ghz and 8ram with 258 SSD. Same price. I value the portability and design of air for marketing job but I may need more power for multitasking and maybe some light photo and video editing. Which one is the better option in this case? Or is it just enough going with Air 2018 with 8 Ram for described performance requirements? Hope that my computer will last for long and trying to make a considerable choice for the future use. Many thanks!
