I am really on the fence on getting a retina MacBook. I am a Cisco network engineer that uses programs such as zoc, ms visio or lucidchart, ms office, Google docs, VNC , Remote Desktop etc. A lot of my work requires having 4-5 programs open at a time and spread out between the laptop screen and a 2nd 1080p monitor. I am enticed by the thought of lowering my footprint from my 13 pro to the retina MacBook but that core m is so concerning. I travel a good bit so it could be beneficial. Any IT pro's riding with this beauty as their main machine? Any issues with multitasking programs? Fairly good chance I'd also have to run a win 10 vm in parallels some as well. Probably just going to grab one for a test run during the holiday return period but looking for some input.
