As mentioned, Expose and Spaces separate and combined are excellent. Seeing 4 (or more) desktops and all the windows displayed in each space is extremely helpful at times.
 
To be frank here though, the Mac OS GUI is so far ahead in terms of design and usability from any Linux GUI, why would you want to run any available GUIs on Linux? I spend the extra money on Macs to get the GUI, without it there isn't much of a reason to use Mac OS X over other UNIX clones.

glad to know your reason.

tell me some detail/example about OSX's GUI is "so far" ahead of Linux GUI
I agree completely... apple made their command key MUCH more useful. IDK why people say OS X key commands are difficult. Whenever you use OS X key commands, all you gotta do is remember 1 thing and that thing is

"THE COMMAND KEY IS THE GOD OF KEY COMMANDS" it's simple, all i do is hold down the command key.

now while holding command key, lets see here I want to close an app
I press Q
I want to switch between apps
I press Tab
I want to copy
I press C
I cant to cut
I press X
I want to paste
I press V
I want application preferences
I press ,
I want a new window
I press N
I want to save
I press S
on and on, there is even more key commands then that, but i just covered the basics

have i made my point clear? ALL the basic key commands revolve around the command key, which makes it simple, because I just gotta remember, the other letters like, C, X, V, N, S, Q, Tab etc.

Maybe Windows has an easier, way but i dont care I find OS X is easy enough.
personal opinions are valuable to each individual, but can't be used to substitute factual analysis for general users. NOBODY holding cmd key all day long in case they want to do this or that sometime with keyboard.

Oh yah i completely forgot about the spell check in OS X.

Does anyone else use the built-in dictionary alot?[/QUOTE]

command tab is god (of your comp😉 )

the best things are things that are hardly noticed. they work so well you shouldn't notice them. as they say in racing. when you have a good seat you will not notice anything about the seat. you shouldn't feel yourself sliding, you can be totally relaxed etc. this is for racing seats with harnesses but does apply to most other)

widget dictionary works well to

i sometimes think 4 is to much. two is enough especially if you have a mbp and use the extended desktop. just go back and forth with two with 4 its a little more cumbersome. i used 3 once for writing codes. but that was 3 colums not rows
