With 140 machines, I second the opinion that sending a PM Directly to @azorin or @zorink is a great way to go. This way, you can explore your options directly with the developers. I am sure they would be happy to help.
In my post above, left click the names as highlighted with the @ sign. A popup window will appear. Upper Right of the window has a message button that you can click to send them a PM.
Another thing to think about is the type of business you have and what tools are included with Ultimate and the support and updates. You can always add and remove as needed. It's Linux. So take what you need out and keep what you want.
I am also baffled by the lack of Message button. But when I used the @ sign above on their names, it also alerts them directly to this thread and that comment.
I think it's because your account is new and you haven't unlocked that feature yet. I believe you have to hang out at the forums a little bit to unlock the ability to DM people. Alternatively, you can just email him.
Oh ok. 120 desktops. Decent size consultancy business. If you have a business that large, the cost of Ultimate is minimal...a write-off. Yet it helps a great cause. So, whether you think you need Ultimate or not for your business is irrelevant as you can always add to the lite version. Think of it as whether you want a great OS, great support, and help contribute to the success of an entity that's helping provide and support the system your business survives on.
I agree with Aravisian. If your a business, 120 machines strong, you should most certainly contact Azorin to discuss business options. Not only could the Zorin team provide you a special price, but they will be the best to answer specific questions related to use of their software, in the business industry.
Hopefully, you will receive a reply soon. I can't tell you how much I respect you for NOT going with Windows 10! Supporting open source is always the way to go, especially when privacy is a concern for your company. Another thing I like about Linux is it gives you the choice to do what you want. Microsoft is all about making the choice for you.
