For me, it's a work tool, not a passion. If this trend continues for multiple years then there will be a reason to worry when considering buying a Mac, as software developers will have less of an incentive to support the Mac platform. But that is only possible if Windows or Linux get significantly better, and, in that case, it won't be a big downgrade to switch away. As of now, the Mac platform is still better than the alternatives for almost any professional, so I'd be surprised if Macs stopped getting good support in the foreseeable future.
