One more: I could try out/ use the app on platforms for which it is currently unavailable, such as my iPad Pro (with large screen and stylus) or Samsung Note 8 (smaller screen but also a great stylus). Someone mentioned the lack of web API for stylus, which is a huge gap right now. I expect that gap will be filled sooner or later. Indeed with WebUSB it should be possible to implement drivers for the plug-in Wacom style devices for the web right now. Since getting these two great devices I haven't plugged in my Wacom once though. The lack of a really good vector app for Android (like Autodesk Graphic for iOS) is what made me curious to check out these comments and see what Krita is about. Yes the web has extra overheads, but it is the cross platform runtime with the broadest reach.
