That's something else that had a tendency to kill a Citrix deal. But implementation details are important. In my experience, managers who worked from home loved it because they could get the complete office desktop experience at home. There'd be some visual lag for sure, but visual latency aside, file and print operations were snappy and reliable. Trying to open an Excel spreadsheet over a dial-up network drive took ages. Print jobs were worse. Most installations I saw were POCs that got used as a remote work solution for managers. Any time they decided to deploy an app to all office staff the thing would predictably fall over, because it wasn't sized for that.
My anecdote is that it works much better than any X Windows setup that I have used, and since around 2011 it is either Citrix or RDP on most of our projects.
If we get projects with customers that will rather hand us low quality Dells with 4 / 8 GB with HDD, to access their infrastructure, I will always advocate for a Citrix or RDP based setup instead, due to how bad those laptops tend to be.
Can such a setup have a lossless presentation of the GUI? Personally I really dislike using a modern computer via a lossy video signal, just as a matter of principle. Same reason I'm not interested in cloud gaming even if the latency is great.
