Pro It's really easy and fun
Vector graphics can be created and edited with Inkscape.
Cons
Con Uses its own SVG-format by default
Inkscape might use SVG as its default format, however this SVG's contains some additional SodiPodi/Inkscape additions that can be troublesome if you want to import the SVG into some other application.
Con Since 0.91 the gradient editor is gone
It is now only possible to edit a gradient on screen. but you can't set a stop to a specific percentage anymore.
Con Y-axis inverted
0,0 coordinates begin in lower left corner, not upper left corner as SVG standards define in Inkscape 0.92.x.
It seems this is now fixed in the 1.0 beta 2 version of the program.
Con Based on the GTK widget toolkit
Software is based on GTK, so it might not integrate well in non-GTK environments. It also requires many dependencies on those non-GTK desktops. It also adds dependencies to GTK-environments since it is written in C++ which requires the gtkmm wrapper/interface.

Comments
Out of Date Pros + Cons
Con Unstable
Sometimes it just crashes without any reason, so it's not really usable as professional application.
Con Newest versions use millimeters instead of pixels
Newer versions use millimeters instead of pixels (and there is no way to change that) which is great for print media but sucks for desktop/digital art.
Con No Gradient Mesh tool
Gradient Mesh or a comparable tool is not available in Inkscape.
