We've already seen some progress with how the new Mac OS X 10.5 Leopard is able to run Windows-based applications on a Mac. However, this latest Microsoft-Apple crossover is sure to get your attention - an iPhone which can run Windows XP.

During a recent demonstration at the Citrix Application Delivery Conference in Melbourne, presenters were able to use a client desktop software entitled "XenDesktop" to access Windows sessions over a Citrix server. This was possible through the use of the UNIX-based Citrix ICA client, which can access Windows on the iPhone via Wi-Fi.

As seen from the images we have above, the iPhone was still able to incorporate inherent features like its "pinch" controls to zoom in and out of the desktop. Only time will tell if even more integrated features such as these between the Microsoft and Apple platforms will be released in the near future.
