This is a great tool to write structured documents. Latex is used in the background to render beautiful documents. It certainly helps to have at least some latex background. I used Lyx to write my Master and Ph.D.. Very good for large projects as books or reports.
Best editor when it comes to math - especially when formulas get lengthy! Instead of LaTeX code you get to see proper mathematical symbols. I use it even as a notepad when calculating.
I use it daily. I have used it for letters of a few pages, and for books of hundreds of pages. Producing a 200 page press-ready PDF with hundreds of figures and tables is extremely simple. Producing a 20 page report takes me about half the time I would take using MS Word because the formating simply takes care of itself.
At first I was like: "meh." But then I read the introduction and tutorial, after I was like: "Holy shit awesome!"
I like it but... it saves documents in ".lyx" format only. Therefore if you want to save a document in ".doc" format it will be impossible unless you know how to change it. But I personally don't want to get into it. I will better use another Word Processor.
Good. I use it to paste data (edit: special paste: plain text) into tables and then copy the code (view: fount code panel) to Texstudio.
No need to compile everytime that you need to see the ouput, this saves time.
Using it for my CV (moderncv template in texlive-latex-extra) and the occasional letter. The generated PDFs look far better than anything MS/Libre/OpenOffice could ever hope to create.
I specially use lyx for building tables for latex. Easy to use, only import to latex code and paste in your latex document..
This is my favorite way to write/edit large documents. It is the best front end for latex and the most powerful tool out there for the creation of books, thesis, papers etc. You get the best of both worlds in terms of control and usability.
I really like it alot. I just wish there was a better way to check grammar . It won't keep me from using it though.
