Citrix XenApp - Windows Apps on Mac.

We've recently completed an installation of Citrix XenApp for a client who has a desktop and laptop estate that is predominantly Apple Mac-based.  

XenApp with published applications has been a great implementation here, as it has allowed us to seamlessly deploy Windows-only applications to the Mac computers. The client is therefore able to take advantage of Windows-only software whilst maintaining an Apple working environment.

This is great for the Mac users as they can continue using the Apple desktop in the way that they are used to, with the published Windows apps behaving like native Mac apps.
