In supporting the enterprise, pretty much every application I deal with is unfortunately "Windows Only". Accounts tends to be managed by MYOB, Quickbooks or in the large firms, Accountants Office (also a MYOB product). All these ship with Windows services, Attache being particularly offensive as it has "known issues" with clients on Windows 8.1 or higher. Pay is often Payglobal or NAV, which again is Windows.

The closest I had was a LexisNexis product that used to run on a Linux server - until our account manager told us they were dropping Linux because, and I quote, "Linux has too many security problems". I've supported two different EMR (medical) products, and at least five different POS products, all Windows only. Even when we get a SaaS product running in a web browser, half the time it's "IE only".

I'd give a lot to live in the type of organisation without this legacy.
