With the advent of tablets and very capable smartphones, it seems that having a full-blown portable computer is becoming unnecessary. Sure, many pros still require a full-blown computer and it is superior for a multitude tasks but for most on the go just as much can be accomplished with an iPad or iPhone. Candidly I have never, not once the entire time I have owned it, felt the need to bring my Retina MacBook Pro out of the house (oddly enough, nor have I felt a desire to take an iPad on the go with me). There was no need nor desire to have to drag around a device that is nowhere near as portable as an iPhone. So even though my 2012 Retina MacBook Pro still feels modern and compares well to the new iMacs spec-wise, I feel that I would be better-suited giving up the form factor and ease of use of the MacBook Pro for an iMac that would in theory make me more productive with its larger display and fixed desk location. If I never need the portability of a MacBook Pro, preferring a tablet or even phone, I see no reason not to have a more comfortable experience (besides the hassle of selling and transferring over to an iMac). Even though laptops seem to be the more popular option, for professionals not constantly traveling it seems to make more sense to go all-in with a full-blown fixed computing experience. That would leave room in a workflow for, say, an iPad Pro, if necessary.
