Needing opinions please. I currently have a MacBook 2017 i5 with 512 SSD and a 2016 MacBook Pro - I have tried using them with a standard monitor in a docking station and it works most of the time. A little about me, sales guys use computer primarily for email, presentation and an ocassional video call or presentation. So here is what I am considering: LG Ultra Fine 4K Monitor and the two hot swap MacBook and Mac Book Pro OR return the MacBook can only get Best Buy credit as it was a combination of gift cards and device trad ins that I used to pay for the unit, then use the proceeds to purchase a iMac. Here is my fear I will not be happy with the fusion drive in the iMac - everything i read says get an SSD, I have had SS's in my computers for years. So it is LG Ultra Fine display and two laptops or the MacBook Pro 2016 and a 2017iMac with a fusion drive. To the best of my knowledge you cannot configure apple products at Bestbuy. OK any and all opinions are appreciated. Will I really notice the fusion drive in the iMac after using SSD's for years. I feel like I am going backwards.
