Although I like LyX, I don't agree with this. If insertion of symbols etc. is of significant value to you, you can do the same in "plain" LaTeX editors like Texmaker and Kile (to mention just two). End, beside that, both editors have autocomplete options which LyX lacks (you have to learn shortcuts in LyX, which are configurable in Texmaker and Kile too). Using LaTeX commands (and custom environments and commands) in LyX soon becomes visual mess and is highly impractical.skibum1981 wrote:LyX is still faster than LaTeX EVEN IF you know LaTeX, at least for me. I agree that writing $\alpha$ is faster than pulling it down from some table, but you can write this in LyX as well; you can use virtually all of the LaTeX commands that you know and love, and some shortcuts too. Plus, you can also create keyboard shortcuts for just about everything. I prefer it to LaTeX quite a bit.
LyX is very limited when advanced and extensive changes/customizations to the document are needed and has many serious problems which are showstoppers for advanced LaTeX users. But, for users who are new to LaTeX, those who don't have to use many LaTeX commands and use templates as they are, it's pretty good. Just remember to keep backups of your files, since .lyx files can get corrupted from time to time.
