I have been using Ubuntu on and off since about 2005. Last year I switched from OSX on a dated macbook to Ubuntu on a newer Dell XPS. On the whole I am happy with the switch: with many of the apps that I use based on electron (slack, atom, mailspring) or directly in the browser (google docs), it is hard to notice the difference. I do most of my work related writing in latex, so this has also not been very noticeable.

I don't like latex slides and I give presentations frequently for work. The only thing that has proved consistently annoying is that LibreOffice Impress is nowhere near as good as keynote.
