I did an audit of the tools and software I need to do my job. All that I need Windows for at work is to run SharePoint Designer 2013 which is part of Office 2013. The rest I can do from a LinuxMint or pretty much any of the other mainstream Linux distributions. Come to think of it even Debian on a Raspberry Pi would do.
Office 2013 was not WINE friendly the last time I checked, so I am a bit stuck there.
