Con No syntax coloring for Latex
The distribution comes with syntax coloring examples for many languages, like Haskell, C, Lisp, Python, etc. However, there is no scheme for Latex. If you need syntax coloring for Latex, you will need to add your own color scheme.
Con Source distribution only
Femto Emacs is distributed only in source form. Therefore, you need to install ncurses, gcc and compile it with make and make install. There is no binary distribution. If you want mouse support, you need to program it in femtolisp or in C. This should not be a problem if you are a programmer, but can become an issue if you don't know Lisp or C. If you want to use femtolisp on Windows, you will need mingw and ncurses.
