I have a macbook pro 15 2.3 w/16gb of ram. I have 5-6 parallels vm running at a time because I deal 100% with windows at my job. The problem is while working, or backing up the laptop, etc, it runs at 90* C and fans run at 6k RPM's. After reading about this, it seems quite normal when the laptop is under load and apparently i keep it under load, quite often. So my question, I have a few days to return the laptop, memory, and external monitor. Should I, or would you replace it with a desktop instead (the company is willing to pay for a nice HP one instead) and just lug around an external SSD with all the VM's? I already have an iPad, and rarely use the laptop as a laptop. But I do work in 3-4 places, all of which I control the environment by either having a desktop or having a 27" thunderbolt. Any advice is helpful!
