Comment Market share, not functionality (Score 2) 244
There are plenty of Windows progs I cannot do without, but it is because of their market dominance, not because of an intrinsic lack on Linux. I've been a professional writer, editor and proofreader for 10 years* (and a Linux user for 25) and as an editor I have never received an ODT file from a client. I saw them a few times working in academia, but they are functionally invisible in (my part of) the industry. I have used LO in my own time, but not stretched it capabilities.
Logically, we should no more criticise LO for not being 100% compat with MS Office than the other way around, but in practice I need 100% MS Office compatibility to make a living. I need the tools like PerfectIt (https://intelligentediting.com/home/) and so on because I need clients. So in that sense there is no Linux equivalent, but if Microsoft did not play games with its file architectures, there probably would be, so that's not Linux's 'fault'. Word is horribly buggy, they keep adding functions without making sure the existing ones work well. I hate it, and I cannot avoid it.
Much as I hate Acrobat, it's another one. We do a lot of PDF markup using Acrobat, and my clients send me files marked up in Acrobat using its commenting tools, and I've yet to find a 100% compatible Linux tool for that. Happy to learn of one. I use a Windows version of Evince to read and view PDFs, but I have to fire up Acrobat for the annotating and editing.
I've never done layout, for which our designers use InDesign, and my PhotoShop and Illustrator skills are rudimentary at best, so I cannot comment on how much Inkscape, Gimp, Scribus (Openshot, etc) are replacements. The question is, if LO and these tools were the 800 lb gorillas, with all the 3rd-party support that that would generate, would we be lacking functionality?
