One of Lion’s biggest new features is totally new Exposé. Exposé’s task is to help people navigate between windows on the desktop. Considering that most of us often have more windows open than we can actually fit on the screen, a feature like Exposé has been very useful. With Lion, Apple has decided to take Exposé one step further and it now goes by a new name: Mission Control.

While Exposé was strictly limited to the apps open in your desktop (or one Space), Mission Control breaks the limits and adds Spaces into the mix. To simplify, Mission Control is just a combined version of old Exposé, Spaces, and the Dashboard.

On the top, you have your available Spaces (and remember, each full screen app you have open will show up as its own Space). You can easily add a new Space by taking your mouse to the top right corner and clicking. The center is taken by Exposé-like app switcher which groups all your open windows togehter by app. If you have for instance three Safari windows open, they will be grouped together. The bottom is taken by Dock, which shows you what apps you have open.

Mission Control isn't as simple as the old Exposé, and if you have absolutely no use for Spaces, then I can see why you would like to use the old Exposé instead. The old Exposé was better at switching between random windows while Mission Control does a better job of switching between apps thanks to its neater grouping.

There is one disadvantage compared with Exposé though: if you minimize a window into app icon in the Dock, that window doesn't show up in Mission Control. The only way I’ve found is to use the Application Exposé, which is still present, by right-clicking the Dock icon and selecting “Show All Windows” (or, if you have a multitouch device, doing a two-fingered double tap on the app's icon in the Dock). For me, this is a big setback as I used that feature extensively and it's now more difficult to take advantage of. 

Some avid Spaces users might also prefer the old Spaces, as you could have the whole screen dedicated to switching between Spaces if you wanted. Now you only have roughly 20% of the screen for Spaces when in Mission Control. It can be hard to switch between Spaces because the thumbnails in Mission Control are so small that you can’t easily see what's in each one.

While it’s not a big surprise, the old Exposé and Spaces are dead so there is not an option to disable Mission Control and use them instead. It's possible that third party software will bring back the old Exposé and/or Spaces, but no announcements have been made so far.

I think Mission Control does great job for the people it’s aimed at: consumers. The average user most likely won’t need more than five Spaces, of which the majority will be full screen applications. For that use, Mission Control is brilliant. Personally, I never used Spaces with Leopard or Snow Leopard but I find myself using Spaces daily in Lion. In earlier versions of OS X, Spaces was a feature that was a bit hidden - there was no dedicated button for it and it didn’t feel as integrated as it does with Lion, and Spaces simply didn’t feel as easy to use. Mission Control integrates Spaces into OS X in a much more convenient way.

    Primarily FAO the AnandTech reviewers

    Thank you for a very timely and useful review of FileVault 2.

    The following microblog conversation links to an overview (work in progress) with some unanswered questions. Comments will be greatly appreciated.

    And it is a big problem!

    The removal of Expose and Rosetta are big reasons not to "upgrade" for me both now and for the foreseeable future.

    A lot of other things are clunky or ugly or annoying (like the inability to control scrolling speed in System Preferences) ... but those are minor reasons not to "upgrade".

    This was a tough review to do, and I love Anandtech, but I think you guys skimmed over some very important negatives. I don't know a single person who is not an Apple employee or stock owner who claims to really like Lion ... come to think of it I haven't yet met an employee who really likes it, so it is pretty much stock owners who are saying it is an upgrade-without-quotation-marks. Although a lot of employees do genuine like the full-screen mode.

    I have a circle of nearly 200 fellow Mac users—real, (mostly) unbiased, not-at-all picky or ego-inflated (I'm not suggesting that you are), everyday-if-not-hour-intensive Mac users—and our experience has been 95% positive or enthusiastic. Some are disappointed with the loss of or change to this or that, as am I, and we have to adjust, go As The Mac OS Turns, but not one isn't glad they upgraded. Any OS must continue to be evolutionary or die. Some things go, others stay, but the overall progress is forward. I will take Lion over Windows 7 hands down this or any day. Windows has its features and (of course) fans but I'm not buying, now or ever, unless something goes massively wrong with current OS development.

    Thanks for an enlightening test! One thing I wish you had tested was the time to wake from sleep. On my macbook air (with very similar specs to your setup), it seems that waking from sleep takes a couple of seconds more with FileVault enabled. This is pretty significant when you are used to the very quick waking of Apple products...

    The reviewer complains that Resume can be annoying for the likes of him/her when a clean slate is desired. He/she writes: "I found myself pressing command-W a bunch of times to close windows before I'd press command-Q to quit the program." There is, of course, the shortcut command-option-W to close all open windows in the active application. For mousers, press option while clicking the red "close window" button does the same thing. Gotta save those clicks!

    I am a work-study at a college and we recently bought a bunch of IMACS to make an IMAC Labs for all the students. We also have a few for the staff. We had Snow Leopard installed initially and we were able to connect perfectly fine to all of the servers within our network,however since our implementation of lion the servers don't show up under the shared tab in the finder automatically like before. The computers on the network show up but not the servers. Anyone have any ideas as to why? I figured it has something to do with samba not being implemented as it was in Snow Leopard? Is there any easy way to change a setting? Or do I have to manually add each server to each computer?
    Thanks
