I don’t think it’s a support issue at least that’s not the hard part. Native Linux apps are generally second rate if you’re lucky. The browsers are fantastic there’s maybe a couple of dozen solid production quality apps out there that working all or nearly all distros.

You can get almost anything you want to be done in Linux, but there are definitely compromises you have to make.

As long as there’s compromises are greater than the compromises you make sucking on Microsoft’s tit, Linux will still be in the shadows.
