I have a laptop.
I've often felt the tingling need to change to another distro, but Mint works and it works well for me. So why fix something that isn't broken?
I use the Libre Office Writer and Pluma for writing. Pluma is like Gedit, but for some reason it's called Pluma in Linux Mint. I write most of my blog posts in Gmail and email them to the blog.I backup things in Dropbox.
I have many notebooks and I write in them regularly.
I also write on my phone. It's an iPhone 3GS. There are many apps, but I use Notes app and email whatever I write to myself. I also use Day.One app to write something daily.
I write on my tablet, too. It's a Samsung Tab 2. The Android diary app Momento is good. I mostly write just after I wake up in the morning. Most diary entries are records of dreams I have the night before.
For fiction writing, I like to listen to Metal before starting writing. But when I am writing, I avoid music or listen to something soft (Sting's album The Last Ship is pretty good).
For any technical writing, I prefer silence.
And that is how I write.
(NaNoWriMo started pretty okay, wrote close to 3K words today)
