Photoshop
If you’re a Linux user who like Photoshop you’re pretty much stuck having to pay the Microsoft Tax just to run it. Over the last several years I’ve largely converted to using GIMP for most tasks and only occasionally switching to a Windows VM for Photoshop. Adobe has said for many years they’ll not support Linux though their support of OSX and their past support of Unix proves they’re capable of it. I’ve also maintained that I’d upgrade from my copy from the aging 6.0 if Adobe’d release a Linux port. And it seems I may get that opportunity thanks to Google
