I currently have a late 2012 Macbook Pro Retina 13" which is starting to age and a 2017 iMac 5K 27" (Core i5 3.8ghz, 16gb ram, 580x Pro 8GB graphics and a 2 TB Fusion Drive), purchased in October 2017 and in perfect condition. The iMac is not used very often because there is no fixed place for it in the house and is therefore removed when necessary. Now an acquaintance is looking for an iMac and suggested an exchange, he has a 2018 Macbook Pro 15 "(Core i7 2.2ghz, 16gb ram, radeon pro555x and 256gb SSD) which was purchased in August 2018 and in perfect condition. What do you guys think of this proposal? Is it a good deal or am I better off selling the iMac or iMac and the old Macbook Pro and then buying a new Macbook Pro when I go to the US in October?
