Think WAN latency. Your shitty VB6 app using some awful circa 2002 middleware dies when you have 80ms of latency between you and the server.

Insert Citrix, and the turd app is 3ms away in the data center and works.

I used to run a 100k user VDI environment. The cost was easily 4x from a hardware POV, but I had 6 guys running it, and it was always consistent.
