Cons

Con Very slow startup on some systems
Depending on factors like how many fonts you have installed, Inkscape can take upwards of 30 seconds to launch.
Con Mac version is in worse shape than Windows/Linux version
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 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
Con Incompatible with previous versions
Sometimes backward compatibility breaks. For example, pre 0.92 SVGs are incompatible with later releases (due different default resolutions).
Con Limited work with ICC CMYK color scheme
Support for ICC color profiles only in SVG files.
Con No support for large printing machine system
No support for large printing machine environment, except exporting the resulting artwork to PDF.
Con Y-axis inverted
0,0 coordinates begin in lower left corner, not upper left corner as SVG standards define.
Con Has ads
Displays advertisements (in a sidebar on the right - no popups etc).
