From the article page:
There’s no shortage of software that can create pixel art, but most applications are either grossly over-featured, meant for photography or graphic design, or under developed, because they are meant for children or for basic graphical tasks.
What makes mtPaint great is that it specializes in pixel art, has a tiny footprint—the application is about 391k, compiled (assuming Gtk is installed separately)—and it is designed to run efficiently on specs as low as 200MHz CPU with 16MB of available RAM.
