Some software just literally isn’t available for Linux. And lets face it, even Ubuntu requires more tinkering than the average user is prepared to do, or in other words, any tinkering at all because they would have to install it themselves and they do not know how to do that. And the few times I’ve bothered to use Linux even as my backup, the tinkering never stops. Its not worth the hassle at this point in time.
