They just don't use X Windows. They use things like ICA.
Fuck all it is.The latency spent transmitting rendering commands and bitmaps are far higher than just running it locally. This design is so 1950's.
X11 is, very literally, 1986 technology. Think 1986. Like really swear-to-god 1986. Like Micheal Jackson 'Beat It' 1986. That was when X11 networking was designed and implemented. It's been pretty much set in stone since then.
Yeah. Have fun in your 'real world' mom's basement.It's a good wish but in the real world, it doesn't really work. It never worked for me.
Those of us that actually implement and support large scale systems know that X11 is fine, but it's hardly the only game in town and it's far from the most practical and most efficient anymore.
You want to see what the real world looks like outside your Linux desktop?
"Now with iPhone client support!"
Take a careful look at company's name at the bottom of the website. They make a shitload of money because X11 networking is simply not good enough. They are used in literally thousands of huge companies world wide. Remote desktop, remote applications is big business for them.
I like X Window networking. OpenSSH integration makes it deadly simple and relatively secure were otherwise it's a total nightmare to use and has just about the worst network security you could possibly imagine. But the world has moved on. Sad to say.
You don't need X to do remote applications or have remote desktops. You don't need Xorg X server running your video card to display, render, or be backwards compatible with X applications either.
I can take any Windows desktop and in about 20 minutes of work get very good X11 compatibility with SSH integration. With OS X X windows is even more trivial to use. It's practically built-in.
You can also run X Windows applications FROM your Windows or OS X desktops. People don't do it, but it's possible. Now think very carefully why people don't do it...
If VNC was the only alternative to X then we'd all be f*king stupid to move away from X. But it's not.
Seriously. Check this shit out:
