Re: I've never been convinced
Common mistake on the dumb terminals. Most just assume that everything is taken care of at the backend with Citrix VDI (like it is with View/Horizon) but the relationship between front and backend with Citrix is symbiotic and terminals need to be chosen with care and a view on users requirements for their job role. Zero's and basic Terminals are fine for task workers who have a couple of apps and no need for voice/video or rich media, however all too often they are chosen on a blanket basis on the misguided advice that they are all that is needed.
Sadly to have more capability you generally need Windows Embedded and all the support requirements and additional costs to go with them.
The above case is exactly what I spoke about earlier, blanket cover and perpetuating the 'cheaper' myth.
VDI makes sense if it is targeted at certain worker profiles that it suits and those that it doesn't are left with a traditional PC and also if your requirement is a highly controlled automated environment with a high degree of data security and not for cost considerations.
