I'm learning how to use this software now and I'm having a lot of difficulty finding features that I highly rely upon in ME and SE. It does have some nice features, but just doing the basic things you would do in ME or SE are now completely different. It's like learning how to walk all over again. Also, it relies on C# for any customized scripting. I've never needed VB scripts in FTView, but Optix relies on this more heavily and I believe you will need to use it at some point. I could see a new installation utilizing this product, but there's no reason anyone would pay to rebuild all of their HMI's on this platform at a mature site where everything is already developed. Perhaps if the site were using a very old version of an HMI that couldn't easily be migrated to FTView. One of the highly promoted features of Optix is developing from the cloud, which just means the software isn't installed on your PC. That's not much of a selling point.
