I am considering. What got me interested again is that I got a taste of the incremental reading workflow through the Anki plugin. I edited the plugin to try and make it feel more like Supermemo (for example to carry pictures from a parent note to an extract, along with several reference fields instead of a single one). But still, the scheduler in the plugin doesn't work and I can't dismiss notes without deleting them, so it is really a makeshift version of what I believe SuperMemo can offer.
I am also enticed by the knowledge tree and the concept maps and the promise of SM-17 being a superior algorithm and all that.
What deters me, though, is that I work on a MacBook pro and there are issues with rendering the fonts on the retina screen. Installing Windows and SuperMemo is not a problem (Parallels Dekstop), but once I launch the app the fonts in the UI are all blurry and pixelated. I am willing enough to try and adopt to SuperMemo's quirky UI but sacrificing the smooth fonts for reading is a deal breaker for me. Particularly because I have so much control in Anki, using CSS to style notes for comfortable reading -- (actually that is the only reason I got acquainted with CSS).
