Most operations have minimal IT Staff. Downtime causes delays and the rebuild of inidividual work-stations could take days. This can cause posting and billing delays resulting in overtime and customer complaints. A Thin Client environment is a versatile environment. Users are not tied to any individual work-station. This type of versatility also reduces the number of work-stations, in turn, reduced operating cost.
Other benefits? Single point of upgrade. Example, a new version of Microsoft Office is announced, This evening you upgrade the software at the server level. Tomorrow morning, all Thin Client users are now upgraded. No need to to workstation to workstation.
Another scenario. How many times have you found users saving documents to the My Documnets folder, or to their desktop? Then one day, their computer crashes, The IT department scrambles to rebuild the computer only to find, the My Documents Folder and the Desktop are not on the daily backup. Sorry, nothing we can do.
These concerns GO AWAY in a Thin Client environment
