In today's business world of startup's making a good product and then selling that product, I can't say that I'm surprised at the acquisition announcement. Though as a VMware Horizon customer with zero ambition or desire to bring Citrix into the mix, the messaging and FAQ does little to instill confidence that over time Citrix will do what they can to persuade existing Horizon customers to migrate to their platform.
I arrived at this conclusion not after reading Chris Midgley's email to all customers (at that point I felt pretty good), but after reading the FAQ. Specifically the answer to the question "Will Citrix continue to sell the current Unidesk product".
Throughout 2016, the messaging from Unidesk was that all platforms (VMware's 2.x and Hyper-V's 3.x) were going to line up and be on par in version 4. Unidesk 4.0 would be the one build that all platforms could deploy and utilize.
But now it seems that Citrix is not planning to go this route. Perhaps what we think of as Unidesk 4.0 (minus VMware support) will be part of the Citrix suite, and then as an afterthought the stand-alone product for VMware will just "be available". Speculation, that's all this is.
As a VMware customer, and as a fan of the Unidesk product, I truly hope Citrix will not force VMware customers to migrate through lack of features, lack of support and/or increased licensing costs. I suppose also that as a VMware customer I should at least begin to do my due diligence and explore what VMware has to offer as a potential 'Plan B' to replace Unidesk in our environment just in case. Time will tell I suppose.
