I am sorry if this is not the right place, but I didn't know where else to ask and I can't find an acceptable answer anywhere online.
I'm considering getting a tablet and would really prefer an Android. However, the most critical requirement for me is the vector graphics illustrator. I am a mathematician and make a lot of drawings for presentations and papers using Inkscape (an open source version of Adobe Illustrator). The iPad has an app called Inkpad (which is not the same as Android's Inkpad), which is just like Inkscape, only it also allows the user to draw a curve freehand and convert it to a Bezier curve.
I was wondering if there was anything similar for Android and if so, how it compares in functionality and image quality to Inkscape/Inkpad for iPad.
