Inkscape instead of Illustrator

Did you know there is a good free alternative to Illustrator?

Inkscape is a vector drawing programs with features similar to that of Adobe Illustrator and Corel Draw. It has a very large feature set, including n-sided object creation, text effects, raster images, gradients, layers, opacity and paths. It can read and write in many formats, including XML, SVG and complies with W3C standards. It can also read AI and SVG files exported from Illustrator. A fine and free alternative.
