Last week I held a presentation for our Sales department. As we sold a lot of Citrix Xantippe over the last few years they wanted me to tell them more about the differences between a VMware View and the traditional terminal server based Citrix XenApp solution. So I made a summery about the differences and similarities. When VMware also asked me about the presentation I decided to translate it into English and share it with you all.
