For me possibly the only thing I've bought in years is Simplify3D - http://Simplify3D.com/ - which is a fairly powerful STL-slicer-to-any-3d-printer magic box of tricks that I'm very happy with. There are open source kinda-solutions that I got tired of fighting.<p>I'm getting pretty close to buying Scrivener - https://www.literatureandlatte.com/scrivener/overview - despite it's various weird interface choices and apparently multiple conflicting codebases for difference OS.<p>I've also run in to the limits of Inkscape and can crash/hang it reliably which will mean a move to Adobe, which I've never touched before.<p>Curious to hear what else is out there?

In the last year:<p>dBpoweramp for, finally, ripping my whole CD collection to lossless. Advantages over itunes: much faster, better feedback on read errors.<p>VueScan for using my old scanner with modern Windows. Just worked.<p>OrCAD because Cadence was running a low-cost promotion.<p>I also upgraded my home use license for Mathematica.
