I write things. Scientific things. Sometimes I send those writings to people, in PDF format. Sometimes I have to curate the length or layout of the file.
I just learned that the same software I used for manipulating PDF files under Windows also has a .deb package version for Linux! And it's the same exact program... same layout, same look and feel, same functionality, same everything.
So essentially, I'm now using all the same software I used under Windows (except for the molecular modeling software... still looking for a good replacement to that)... LibreOffice as office suite, SRWare Iron as browser, PDFsam for PDF manipulation, FoxIt Reader for reading, annotating, signing PDF files... why would anyone use Windows nowadays?
What I'm missing as an Author when I writes is a spell checker that is as good as Office365. I haven't seen an alternative yet. Though WPS office mimic Office365 the language support is horrible unless you speak top 6 language of the world.
