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.

    that's pretty neat. It looks like it adds in a bunch of interesting features. The one trend I do see it that both mac and M$ are driving components from there mobile platforms into there desktops. I don't mind if they do this, but I still want a different feel between devices.

    As for the complaints and shouts of if its a service pack that should be free, or if its an update worth 30 bucks. On this subject I think that there is no comparison, M$ has a setup that benefits its use of massive volume licencing, but the option to pay for service packs makes sense for a company that does not dominate 90% of the market, but want to maintain more talent to add more features. I know that some people might take offense to this, but its my opinion so screw you.

    Still confused on the full screen thing, I can move between applications easily, with all of them in full screen, its called ALT+TAB, or Win+Tab, or CTRL+TAB (when you want to cycle through your web browser only. so the entire portion where he says its a advantage over win (this feature) makes me confused, then again i'm a big fan of keyboard shortcuts, so i could be missing things. I'm hoping that the full screen feature pans out. I am considering getting one, but not till they leave the OSX family. (still hate the way it came to be >.<)

    the movement away from CD is great, here's hoping that there are plans in the works for all software to be distributed like this, because... I cant remember the last time i walked into a store and asked myself what program do i need...

    Over all it was a interesting read.

    I just installed Lion on my circa 2009 MBP 2.53GHz C2D. I then tried to download the latest Parallels update via WiFi using Firefox 8 beta and was getting phenominal transfer speeds of more than 900kB/sec for the 203MB download! Wow!

    None of that sounds wow worthy...

    Or applicable to the article...

    About future support for the white MacBooks, it appears that Apple has silently discontinued them. They're nowhere to be found on the Apple Store website.

    Engadget also reported that they received word from Apple that they really were discontinued:

    "Also missing is the button in the upper right-hand corner that would invoke icon-only view - those of you who use it will have to become acquainted with Alt+Command+T, a keyboard shortcut that toggles this change."

    Should be Command-Option-T.

    So with my early 2008 Mac Book I already took a hit to batter life with Snow Leopard. In fact, I just got a new battery and after a couple of months the health reads at 80%. I have seen other's with this issue but the posts often get deleted on the main apple forums. Now I would take another hit to upgrade to Lion?

    I really liked my MacBook Pro when I got it, but this blatant disregard for current customers in a push to get people to upgrade is ridiculous. My laptop has plenty of power for laptop tasks. I don't need to upgrade hardware for performance reasons.

    Remember how much crap Microsoft took for making Vista a system hog on older systems? Do you think that Apple will ever see anywhere near the rage?

    Then don't upgrade.

    What are you so angry about? Your mac will work just like it used to. Apple will continue to provide security and other updates for at least three years. You'll get iTunes and Safari updates. What's the problem?

    If you find you HAVE to have some Lion feature, sell your MacBook on eBay --- you'll get a surprisingly good price.

    The 64 bit support isn't entirely an Apple issue. It is Intel that treats 64 bit as a feature to be hacked out of CPUs on a whim to make them "cheaper." It just bugs me the way its been handled by everyone but AMD. 64bit sure looks like the future, but here we are dragging our heels on support.

    Anyway, does OSX support SMT? I thought that it didn't, but I see the latest specs of hardware with the 2/4 core/thread configuration.

    Ehh? SMT is a processor feature, OSX will use as many cores (real or virtual) as you can throw at it.
