Should thin-client hardware replace the existing desktops in a VDI?
Not necessarily. True thin-client terminals provide additional benefits such as reduced IT support and hardware costs. But in most cases, the existing desktop PC hardware can easily be converted for use as a remote desktop, either by installing a specialized thin-client OS (Linux) on it or customizing Windows by uninstalling everything but the remote-access client and launching it upon startup. A good approach is to use your existing desktop hardware as remote desktop clients and phase in true thin-client hardware over time as the desktops are retired.
