When did it appear in Linux window managers..? I saw it first on BeOS in the late nineties.

From http://en.wikipedia.org/wiki/Virtual_desktop

Switchable desktops were designed and implemented at Xerox PARC as "Rooms" by D.A. Henderson and Stuart Card in 1986[1] based upon work by Patrick P. Chan in 1984. This work was covered by a US patent.[2]

Switchable desktops were introduced to a much larger audience by Tom LaStrange in swm (the Solbourne Window Manager, for the X Window System) in 1989.

Remember, X Window does not equal Linux, UNIX or any other OS. It runs on top of those OSs much like older versions of MS Windows ran on top of DOS.

UPDATE: doh! knightWRX beat me to it.
 
Does the MAC OS X Lion for developers (trial) has an expiration date?

Nope. I still have Leopard beta's that were pretty cool and run well. There will be more beta's as Apple works closer to the GM and commercial release of OS X 10.7.

Seems quite nicer than snow leopard, lots of good improvments but I am wondering what would be the minimum and recommended requirements ?

I have got 2010 mbp 13inch, would that be enough ? will be is as fast as snow leopard ?

2010 then your in. I could not see them dropping support for a year old machine!

I've run Lion on the same machine and it is very slick. I don't think we have any concerns ;-)
 
youtube hates my country :(

Yeah I've read comments that some in Germany and others countries can't view the videos due to the music the video may have (someone mentioned Sony blocked the video). What's the story? I'm surprised this doesn't happen here in the states.
 
Unless there are major speed gains for my current apps running on a Mac Pro I see nothing that compels me to buy this. LaunchPad is pointless (Apps folder, Dock or Spotlight work fine) and I have no multi-touch input on this machine.
 
i am super impressed actually. Mostly by the new spotlight actually. That feature right there would be all an OS would really need.

Someone said this early and I agree with them, that it appears Lion is "training" us how to use OS X (XI) as a touch based interface. Some of the things in the video seemed a little awkward (or pointless) to do with a mouse, but a finger, yes a finger would be much better.

Lion is king of the jungle, there is nothing above it. Could this be the last version of OS X before the touched based Mac OS (XI) arrives?

I'm just rambling. Need coffee.

D.

Yes having a gesture based input device would be essential I think. The movements on a 2010 MBP are really slick.
The thing that threw me was they have reversed the vertical direction you scroll in Safari. It is just like iOS now. I didn't realise they were different untill I tried scrolling down a page and it kept bouncing up to the top.
I think anything that inputs gestures; magic mouse / track pad etc will be a must.
People cried fowl when OSX wasn't present on the iPad - the reason for this has been made obvious but I do believe that is going to come to fruition in the very near future.
Some of these current hybrid dual booting laptop / swivel around laptop netbook devices are interesting but clumsy. I expect Apple to show the way in this area.

There are under the hoods improvements, and this is the first rough beta. Implementation of full cores, improved 64-bit system implementation, TRIM support, AirDrop and other file sharing advancements/improvements, OpenGL 3.0+, improved Time Machine with local snapshots (on the forums it's been discussed that "local snapshots" is in its infancy and will have substantial improvements), and even though I never used spaces I like the iOS-esque implementation (even though I dread more iOS features in OS X).

More will come with time. I'd like to see an improved Finder (HFS+ is wearing thin), TRIM support for more SSD's, a unified UI with colors (grey icons are terrible, people are more psychological tuned to identify by color not word/icon - google "The Stroop Effect"), and somewhat off-topic better Pro-Apps.
 
... a unified UI with colors (grey icons are terrible, people are more psychological tuned to identify by color not word/icon - google "The Stroop Effect")

For a guy with really bad eyesight I disagree, grey is very easy for me to read, icons make it very difficult. Ordered lists of text are the easiest way to find things, which is why I use spotlight all the time. Ever tried to find a function in Office for Windows with that stupid freaking ribbon? An example of how colour icons can be a detraction from function.
 
just looking at the video, the ui looks a little confusing switching between spaces, expose, fullscreen mode and that quick launch tool. overall it looks solid, especially the updated spotlight.

My dad is a diabetic who has lost the vision in his left eye. I set up Lion as with Mouseposé and a few other third party apps (which might be helpful to you :) ), but he hates the grey icons.

The Stroop Effect:

In psychology, the Stroop effect is a demonstration of the reaction time of a task. When the name of a color (e.g., "blue," "green," or "red") is printed in a color not denoted by the name (e.g., the word "red" printed in blue ink instead of red ink), naming the color of the word takes longer and is more prone to errors than when the color of the ink matches the name of the color. The effect is named after John Ridley Stroop who first published the effect in English in 1935

ex. Say the color (not the word) and notice how well you do:

blue green yellow red orange blue green purple grey

I watched the video and learned a few features I hadn't seen. There are a few not mentioned, such as "Signature" in Preview. Using your iSight camera or such, take a picture of your signature. I assume this will allow you to use it digitally, which may come in handy when sending formal emails or faxing from your OS. A few more iChat/Photobooth backgrounds have been added for fun.

One issue with "Local Snapshots" in "Time Machine", it stores the snapshots on your main HDD, not "Time Machine". This means that over time your main drive may be loaded with snapshots and if your main drive fails you have lost them. It's been noted it's a feature that will definitely evolve.

am i the only one who finds Launch Pad pretty pointless? You've got the dock for your most frequent apps, and then the apps folder as a stack in the dock for all the others? Does Launch Pad improve on this at all? I'm usually not a hater of new features, i'm always up for new stuff, but this one just strikes me as totally redundant.

I look forward to using it. IMO the Dock looks way too crowded once you pass 15 apps or so. But an Applications stack isn't really easy to organize or use at a glance. It's basically just an alphabetical list or a big grid that isn't sortable.

Launchpad has big colorful icons, is completely customizable like iOS, and becomes invisible when I don't want to look at it. To me, that's the perfect way to sort, view and launch apps. Of course, the old methods of launching apps will not be gotten rid of if you prefer those.
 
I'm sort of worried about Apple more or less forcing Spaces on us. I think Spaces is GREAT if you are working with a small monitor. On a bigger 27 inch cinema display or dual monitors, I find myself not using it so much since there is so much screen to work with.. Looking at my Desktop right now, I can see 7 open programs at once across two monitors

Whenever someone sits down at my work station, launches a program, and the Spaces slide over to reveal the program, they are most of the time super confused and wonder where the other program just went! I'm really surprised that so many people are unfamiliar with it.

I think the opposite is true. They're not forcing Spaces on the user at all. But IF you use Spaces, it always reminds you that its there, and how it is arranged, in Mission Control. I stopped using Spaces, but this might just get me using it again.

When you click the Applications stack icon, start typing the name of the application you want to open and you'll see the icon for the application will be selected and you can just hit Enter.

Launchpad seems cool, but I find that the Applications stack is good enough for me.
 
Disappointing User Interface

Why drain the color from the Finder sidebar (just like in iTunes 10)? OS X is becoming so grey and pale and lifeless. Reminds me of Windows 95 more than anything.

Looks like the Finder "path bar" at the bottom hasn't changed or improved either.

Lion has a lot of good new features, but the new Finder seems to fail.
 
"This video contains content from Sony Music Entertainment. It is not available in your country."

WTF! anyone got another link?
 
I still don't get this fullscreen crap. I've got a 27" iMac. I never want anything to take up my full screen. I mean can't I maximise anything now and make it fullscreen if I want? Even toss it in it's own Space if I want? What am I missing here?

you answered your own question, dude. youre on a giant 27" monitor. try working on a notebook someday.

everything isnt you. if only we could all remember that...
 
I've been using Lion for a good while now and I can tell you that:

1) Launchpad is useless. you'll try it but never use it again.
2) The new Spaces are terrible and plenty of bugs (if I have a finder window open in space #2, and want to go back to space #1, it immediately returns to space #2 and puts the finder window upfront. then i have to close it, in order for spaces to accept to go to space #1).
2) the new finder with gray icons is very confusing. with the colored icons in snow leopard, you could distinguish very quickly if you were on the downloads folder, the app folder or the documents etc. now its all gray, and you really have to spend a few seconds there to find what you want. they also changed the orders of the icons. all this = terrible changes. it will confuse people.
3) why is the new quickview white, again? why can't it be transparent? the only good thing is the fullscreen - but if you're viewing one picture out of a folder with several other pictures, the arrow keys on your keyboard won't help you navigate - meaning you won't be able to change pictures - you'd have to get out of fullscreen, click the arrow key to change the picture and go back to full screen. AGAIN, useless.
4) scrolling gesture is now inverted. it's not touch screen, so why is it doing like an iPad? Im not touching the screen, so it doesn't make sense. if i was touching the screen, it would. everytime you try to scroll down and the window scrolls up, feels like I'm being trolled.

There are plenty more rants, and I can safely say Lion is a bad update. At least from my experience. Snow Leopard is far superior.

This analysis is spot on.

Plus there are many reports that Lion is way more resource intensive, slower, and a memory hog with the auto-save and versions. Not efficient, just an ATTEMPT to be flashy. WTF. :(

You can change the scrolling back to "traditional" scrolling in Mouse and Trackpad preferences.

Local snapshots (I assume this is "versions") is an option, and it's a very rough draft. Engineers/Cupertino has stated it will change dramatically, as will many features.

Under the hood, it makes better/full use of multi-cores, 64-bit. My only beefs are the lack of color, iOS features moving into a desktop environment, AirDrop not functioning on some Broadcom Airport Extreme cards (year doesn't matter), and Launchpad being completely pointless (moving applications one at a time when there are 10+ pages, and app icons show for applications that no longer exist and restarting brings back deleted icon and empty folders can't be deleted).

What's with MR auto-lowercasing the first letter?

I'm not a fan of Quicklook losing it's dark transparency. Now it looks more like the window of an app. That's about the only thing that bugs me at the moment.

It's quite apparent to me that this is going to be one of the most feature packed updates for OS X.
