I currently have a 2012 Mac Mini that I upgraded with an internal SSD and have a 2 TB USB 3.0 drive connected to. I had to relocate the machine to a different room that does not have ethernet, so I am now connecting to my router via WiFi. I was thinking of getting a MacBook Air and thought...instead of adding the MBA, can I sell the Mac Mini and use the MBA as the desktop replacement while having the option of disconnecting and taking the MBA with me to a different room or out of the house if I need to? The majority of the time I'd be running it connected to the monitor in clamshell mode. The primary con is the hassle is connecting and re-connecting each time I move it from the desktop. I'd also have to be disciplined to properly disconnect the external USB drive each time (since it's shared and houses my iTunes library). I'd also have to leave it on all the time (like I do now with my Mac Mini) so files can be accessed. The pros though are that for wireless, I'd be connecting AC instead of N. And that I'd have one machine to log into each time instead of two (most files are on Dropbox or that USB drive though). And of course the flexibility of a laptop. What do you think? Thanks!
