Another of Lion's much-hyped features is Resume, the ability of the operating system and of individual apps to restore themselves to their last-opened state. Unlike Versions, support for Resume doesn't appear to require any effort on the part of developers.

When shutting down or logging out, the OS will now offer to reopen your windows when you next login - you can opt not to, but the option is enabled by default.

Individual apps will now do the same thing - if you quit Word or Preview with items open, all of those items will reopen the next time you launch the program. This is only optional to a degree - there's no way (as best as I can tell) to disable resume for an application for a single instance as you can do with the OS. Your options are limited to enabling/disabling Resume for the entire user account using the control found in the General control panel.

OS X stores information about application states in each user's profile, specifically in the now-hidden Library folder. Navigate there and open the Saved Application State folder, and you'll see folders for storing the states of every app you've opened on your Mac.

As with many of Lion's features, whether you like Resume will probably depend on how you work. In certain situations - crashes and restarts due to updates, for example - it's convenient to have all of your windows spring back open. Resuming individual apps was a bit more annoying - I actually like getting a clean slate when I reopen programs, so I found myself pressing command-W a bunch of times to close windows before I'd press command-Q to quit the program.

The main trouble for me is that all of your windows re-open whether you're just launching the program from the Dock or whether you're trying to open a specific file - I'd double click a Word file and get four different documents open at once instead of the one I actually wanted.

At best, Resume makes restarting your computer less troublesome than it once was. At its worst, it encourages and enables bad user behavior - the sort of people who will appreciate Resume the most are the same people who leave dozens of unused windows open in the background at all times, sucking up RAM and slowing down their computers. I can't tell people how to use their computers, but I can scold Apple for helping people use them poorly.

    $29 is indeed a solid improvement. However, given the Mac Store now being out there, their desktop OS should follow the formula of their mobile OS: Free to upgrade. These features are nice but I can't help shake the feeling that these are Service Packs (because they are). And with their "app" store available on the OS and the means of most of their cash inflow, it makes more sense to make this a free upgrade for everyone instead of a $29 upgrade.

    Service packs? Are you serious? Read up on the changes and try to come up with one service pack that changed as much.

    Some people…

    XP SP3 would be a good candidate, but yes, 10.7 is a bit beyond what one could reasonably call a Service Pack.

    You're thinking of XP SP2, and if you have to go back 7 years to come up with a comparable "service pack", it's certainly fair to say OSX 10.7 is more than a service pack.

    I fail to see how the age of the service pack matters. Xype asked for an example and qualified nothing.

    Are we really going through the tired argument that every 10.x update to OS X is just a service pack and should be free? Then at what point should Apple try to recoup costs for OS development, because even if individual point updates are evolutionary, going from the original 10.0 to 10.7 has got to be a major change in anyones eyes. And the same questions could be raised about Windows NT 6.1 aka Windows 7 where the server version is bluntly labeled Windows 2008 R2 and Windows NT 6.0 aka Vista/2008 or Windows NT 5.1 aka XP and Windows NT 5.0 aka 2000.

    Besides, even if you discount the user facing changes, Lion has seem some major security infrastructure changes. Both the 32-bit and 64-bit kernel have been rewritten with full NX-bit and ALSR support as in place in Windows Vista/7 addressing the major security complaint Charlie Miller had with OS X. Application sandboxing frameworks are now available and soon to be mandatory for Lion apps in the Mac App Store which I believe is a security feature that even Windows isn't pushing yet. With the dropping of the Core Duo, the Lion has also be rewritten to make more use of SSSE3 instead of just SSE3 as pointed out by the Hackintosh community. Lion isn't just Snow Leopard with a few features added on top, but the entire OS has seem updates at a low level even if the user might not necessary see all the differences.

    And about the App Store being a major source of income for Apple, Apple has consistently said they aim to run their stores as a break even venture.

    I'm not clear if the iTunes Store in the graphic in the above link includes the App Store, but at the very least as an example of Apple's digital store, the revenue stream really hasn't increased in the last 2 years. Apple's sales growth is clearly from their hardware, iPhone, iPad, and even Mac.

    $1,634,000,000 in revenue from Other Music Related Products and Services (3)

    (3) Includes sales from the iTunes Store, App Store, and iBookstore in addition to sales of iPod services and Apple-branded and third-party iPod accessories

    I'd say their goal of a break even venture is not an accurate description of their stores. Hence the creation of the MAC Store. It sounds like a nice thought, but Apple is in business to make money and it seems their VERY good at it. Perhaps their projection analysis was a bit off.

    Hey, this is good news for the investors and I understand that they are a business. Lets not be too naive and just don't drink the cool-aid.

    Perhaps my finance terms are wrong, but I'd hope the Apps Store is taking in revenue. But if Apple should be offering some of their other products like OS X updates for free, shouldn't we be concerned with whether the App Store is making major profits, such that there is money to spare to pay for OS development?
  • solipsism - Wednesday, July 20, 2011 - link

    Revenue ≠ Profit

    They've paid billions to both developers, and music and video cotent owners. They've also spent money on the infrastructure to support their stores. I'm sure they're making a profit as all good for-profit companies should, but it's not the cash cow you've attempted to present here.
