There are lots of reasons I absolutely despise my 16" MacBook Pro and the heat while plugged into an external monitor is definitely in the top 30 or so. Really don't understand why people are buying these garbage computers.
The amount of defects and other miscellaneous issues I've encountered, along with numerous productivity losses moving from Windows and Linux. Makes no sense. My computer needs to function as a productivity machine. I don't have time for it.
Next laptop(s) are going to be ThinkPads. Because I can buy two for the price of a macbook. We program for Linux servers anyway.
