Windows Desktop VDI solution
Hi David,
I answer your question by pointing you to towards the POC Desktop, a company I am a Director of, which is not something I would normally do, but feel that we have a cost effective solution available for the Charity that you are associated to. I hope this is not in breach of any rules.
POC have recently launched a low cost hosted desktop solution enabling micro and small businesses to get the same hosted services normally only available to larger enterprise sized organistions. You can start with a single hosted desktop and add to this as many additional seats that you require, and each can be set up with the end user in mind. The POC solution means than you do not need to spend any time setting up you own virtualised servers, nor do you need to purchase or maintain any hardware, so can simply use your exiting laptops or PC's as thin client devices, or puchase new thin clients or Raspberry Pi's as Phil W suggests (provided that Citrix receiver has been installed on the Pi)
We are more than happy to set this Chartity up with a free pilot and can offer discounted Charity pricing, so please do get in touch.
