Don't kid yourself that IT systems never change, we've been around long enough to know that you can never be sure when the next piece of hardware, operating system or update can throw a spanner in the works for many companies with strict platform specific hardware requirements - just look at the problems caused by Windows Vista. We develop on a true cross platform base, we recommend Windows or Mac machines, but can support Linux just as easily and we don't need to worry about operating system versions, either, be it XP, Windows 7, Snow Leopard or Tiger. You don't need to worry about whether new machines will work with SQLWorks - the sales reps who want a Mac can have one, and they'll have access to the same features and functionality provided in the windows version as we develop and deploy to both at the same time. We can even develop on different mobile devices, so you can access your data remotely.
