So to you Quartz is just a Compositor. In general, the term Quartz or Quartz technologies can refer to almost every part of the Mac OS X graphics model from the rendering layer down to the compositor. In this use, the term covers Core 2d, Core Image, PDF Kit, Core Animation and Core Video as well. https://developer.apple.com/referencelibrary/GraphicsImaging/idxQuartz-date.html
OTOH, X is "just a protocol".
Don;t know what's wrong with X? Read "Papers and Talks by Keith Packard":
I've read them. If you read them all, then you'll know that most of the later ones are about how they solved the problems identified in the earlier ones.
Yes but a lot more still need to be done. Keith identified a lot of X's problems can't be solved at X's level and should be fixed at "above xlib" or whatever. Some of them freedesktop.org is working on. some were lost. e.g. color management system.
Keith also talk about compressed image transport. Today, to display a jpeg file, an x client (eg firefox) decompress the jpeg and send the decompressed image to remoteX. If X is used oven ssh, the image will get jpeg decompress and compressed by ssh and decompressed again at remoteX... While XIE is dead, I'm sure Google Chrome OS will get it right.
"The only serious improvement I've seen suggested over the X model is to provide a vector scene-graph API so that you can store the entire sequence of drawing commands in things like OpenGL vertex arrays in the GPU's memory. While this is a nice idea, it would require a radical redesign of all existing GUI toolkits and applications to be used to its full capability."
...
No it didn't. OS X uses the same rendering model as X11 with the Render and Composite extensions. Every window in OS X's window server is just an off-screen pixmap, just like X. The window server then composites them together. The only difference is that OS X hard-codes the compositing policy into the window server, while X11 separates it out into a compositing manager, making it easy to replace.
Quartz use a PDF like vector object model. With Quartz Extreme the whole thing is GLSL running on GPU. X itself don't have anything like that and have to use addon like Cairo. Since most X apps don;t use Cairo, even if there is a GPU accelerated Cairo, most apps don;t get any speed up.
"OS-independent remote display (e.g. show a GUI on a Windows machine or a Mac from your *NIX netbook)."
remote x need high bandwidth and low latency networking. Especially round trip issues. So it works OK on LAN but suck on the internet. Most users use vnc and or nx anyway. Anything is faster than remote x on internet. If X did it right the first time there is no reason anyone would ever need nx. (NX is basically a roundabout way to get around X's problems/bugs/limitations to make it works in real live situation. It's written by people really use X and know all the low-level problems. Amount other thing X protocol is very verbose, often send redundant and repetitive parameters over the net. NX try to cache/compress/delete those parameters to save bandwidth) BTW, Google just release Neatx, an Open Source NX Server http://google-opensource.blogspot.com/2009/07/releasing-neatx-open-source-nx-servier.html
remote X's #1 problem is round trip delay. To solve that problem, browser use client-side javascript. So X need some sort of server-side scripting. I'm sure Google Chrome solve that problem already!
"The only serious improvement I've seen suggested over the X model is to provide a vector scene-graph API so that you can store the entire sequence of drawing commands in things like OpenGL vertex arrays in the GPU's memory.

Bingo. OSX did it. overall X's #1 problem is toolkit. Anyone still use Xt? On X everyone write their own toolkits. "radical redesign of all existing GUI toolkits" is easy to do if there is only one standard toolkit. Similarly X have multiple window manager, so any real improvement require radical redesign of all existing window managers.
To put the performance of the machine in perspective, Thomas P. D'Agostino, the administrator of the National Nuclear Security Administration, said that if all six billion people on earth used hand calculators and performed calculations 24 hours a day and seven days a week, it would take them 46 years to do what the Roadrunner can in one day.
I also notice some media change "hand calculators" to "handheld computer(s)" (USA today

Anyone know the list price for MSOffice, Photoshop, Nero and Norton Antivirus/spam/spyware etc. cost???
Going along this line of thought, you can easily come up with however high a number you want. (i.e. "Blender replaces Maya, so there's $6000") The response you'll always get is that since most of the Free Software is also available for Windows, none of these savings are innate to Ubuntu.
Ubuntu is the "Full Unlimited" version. People are comparing it to Vista Home!
While some Free Software are also available for Windows, you may or may not be able to install them on Vista.
For example, you can't use Virtualization with Vista Home. EULA limit.
"PatchGuard" and other security thing prevent you (or at least make it very difficult) to install any free antivirus/spam/spyware and a lot of low level stuff like virtualization, vnc, samba on any version of Vista.
Cheap Vista only supports 8GB of RAM.
AFAIK SAMBA support umlimited users, vista home only supports 5-10 peers!
Cheap vista don't have IIS, dual processor (two sockets) support and I'm sure a lot more stuff I don;t know/remember.
Also Ubuntu have VNC and Xwindow is client server anyway, so compare to cheap Vista without terminal service is totally wrong.
This basically never comes up. Large deployments use volume licensing, and home users mostly don't use remote desktop connections. Sure, it's useful for someone else to provide support for your system - but making the tech's job easy isn't something that people think of when they buy computers.
if you have computers at more then one locations e.g. home/work/school/friends/families. You need remote desktop.
What do you do when your mother have problems with her computer?
Linux is multiuser too, which vista can really support multiuser??
Even XP handles this reasonably well. I'm sure Vista does too.
Not those cheap versions of XP and Vista. Amount other thing how can you do multi-users without terminal server anyway??
Ubuntu is worth $1000 or more if you have to pay for every single utility etc.
The actual number, in dollars, will be different for every user - and they're the only one who can really do a cost comparison for themselves. Enough to say that if you go with Ubuntu and the included software meets your needs, you're *done* with paying for big pieces of software and their upgrades for a very long time.
True, just that people have to point out all those software are there. Pre-installed on the Dell Ubuntu PC and ready to use. Ubuntu is the full unlimited version. All software are full version not home and student version. So even excluded all applications Ubuntu is still much more than Vista Home.
Let me put it this way. Is there any reason NOT to compare Ubuntu to a Vista Ultimate Server Edition?

The demonstration will consist of two 1394-enabled CWave(TM) UWB transceivers, one in the Trade Association's booth and another in the Pulse~LINK booth, with splitters and several hundred feet of coax cable between them. 1394 HDTV audio and video will be streamed bi-directionally between the two booths in the HANA suite, showing how coax cable in the home works as a broadband backbone with 400Mbps application layer throughput for seamlessly transporting multiple simultaneous streams of digital content to 1394-equipped devices throughout the home."
