Who are you, and what do you do?
I'm Andy Weir, and I'm an author.
What hardware do you use?
I have an Intel NUC running an i5-7260U CPU with 16GB of RAM.
And what software?
The OS is Windows 10 Pro. I use Word 2013 to do my writing.
What would be your dream setup?
Pretty much this. I'm not into video games so I don't need much power. The most processor-intensive thing I do is Photoshop from time to time. I like using the NUC because I often have to take long business trips of up to two weeks. Rather than rely on my laptop, which doesn't have all my stuff installed, I like to bring my NUC with me in my carry-on luggage. Then I buy a small monitor wherever I'm going.
