I work out of my home office. Working from home has it's benefits, like no commute, and gives me the opportunity to be in full control over my workspace. I do most of my work on a Retina 5k 27" iMac 3.4 GHz Intel Core i5 running the latest software and OS. I don't often go mobile, but when I do I'll use a rusty old 2009 MacBook 2.0 GHz Core 2 Duo or Dell Inspiron Intel Core i3 with Windows 10.
The apps listed here are ones I use on a daily basis to get the job done.
