I use a laptop so most of the time I write on my lunch break, somewhere secluded where I won’t be interrupted. Noise cancelling headphones pipe muisc from the playlist on Spotify that I create for each novel I write. I use either GoogleDocs or Libre Office’s Write, which is a free word processor very much like MS Word. I use Ubuntu on my laptop. I use a Microsoft keyboard and an HP wireless mouse. My external monitor is an HP. When I write at home, I sit at an oak wood writing desk that belongs to my wife and looks out into our backyard from our master bedroom.
There are some books on writing craft, a water bottle and sometimes a speaker for guitar jamming breaks. Someday, when my kids leave the house, I will get my own writing den. But that’s not likely to happen for quite a few years on.
I made the switch to Linux from Mac years ago and have never looked back. There’s nothing that I can’t do on Linux. I don’t game or enjoy spending money on proprietary software and I hate dealing with viruses. So work gets done and I don’t have to mess with the OS very much.
I’ve never used Windows to write my novels. I used the hell out of an old white plastic MacBook, but Apple decided not to support it and the case literally fell apart over time. So I went back to Linux. I’ve used all kinds of distros but have settled on Ubuntu because I just don’t like to mess with all that anymore.
