I am using 10ZIG clients in production for a segregated environment on Horizon 6 and 7.
The Configuration Manager is free and very easy to use. You can deploy configuration (to a single unit or group of units) to your thin clients over the network using a graphical interface which relies on PXE boot. If PXE boot is not allowed, you can also deploy thin clients using USB pen drives containing different configuration files.
There is also a possibility to manage your client environment now over the internet using the cloud manager, however I am not using that.
The nicest thing though is that you can easily swap from thin to zero clients at no additional cost. Just ask the support team if you can have the other image files for the models you have purchased.
10ZiG will support both PCOIP and Blast extreme, so no worries there either.
So far I am very satisfied with the model I am using (the ancestor of the model you have ordered)
