Thanks @redflagdealsguy ! Have you tried or had any hands-on time with each of the models? I'm using a 2013 MBP right now and it's been mostly fine, but starts chugging when I have more than 5 tabs open and can't handle light gaming. Can you comment on the general portability and cooling/fan noise on any of these?
Not needing to carry it around with one hand all the time but being able to use it comfortably in bed or on the couch sometimes is something I'm curious about.
