One of the reasons I'm so thrilled with Figma and that it completely covers (and more) what I had to use Sketch for...I'm now seriously entertaining the thought of migrating from Hackintosh (on a laptop) to Linux for my web dev / UXD stuff, and potentially just using KVM / Xen for any rare cases when I'd need OSX...For now, I think I'd just sorely miss Postbox (can anyone recommend a Linux alternative?), that's actually all I can think of...
