For those of you worried that Apple's "back to the Mac" marketing push would result in an OS X version that sacrifices functionality in favor of imported iOS features and reduced capability: those fears are, by and large, unfounded. The iOS-inspired functionality is mostly laid over top of a foundation that's more or less OS X as it has been since Leopard - a solid, mature and full-featured desktop operating system.

That said, the usefulness of individual Lion features will likely come down to your individual needs and work patterns. Most should appreciate solid new features like Versions, the new Mail, and the much-needed enhancements to FileVault, but features like Launchpad and the UI overhauls of iCal and Address Book are of dubious benefit to users, and other heavily-promoted features like multitouch gestures and the Mac App Store are already available to Snow Leopard users.

Even so, at $29, there is really no reason not to buy Lion unless you really need Rosetta support (though generally speaking, unless you absolutely need a Lion-only feature, it'd be wise to wait until 10.7.1 or 10.7.2 to make the jump, just in case), and this $29 expense covers every Mac associated with your Apple ID. The price makes Lion a real bargain - full OS X updates have typically cost $129, and Family Pack licenses for five Macs used to cost $149. Business customers can get Lion for $29.99 per copy in units of 20 or more, and educational institutions can buy it along with the latest iLife and iWork upgrades for $39 in quantities of 25 or higher. Especially when compared to Microsoft's complicated and expensive Windows licensing, these simple, low and clearly defined upgrade prices are extremely welcome.

The real question is - what comes next? With OS X picking up some iOS features and iOS 5 promising to become almost entirely independent of our computers, many predict a future where the two operating systems eventually merge into one, and this doesn't seem entirely unlikely (though I suspect we'll hear about new hardware made for this purpose before we see software that does it).

The biggest question I have about OS X's future is whether the Mac App Store model will ever become the only way to install programs to your Mac, as it currently is on iOS. Such a system is not without its merits (users get a streamlined way to buy programs and a system protected from malware; Apple gets a healthy share of the profits), but for many, this would represent a fundamental (and, perhaps, intolerable) change to the operating system.

It's very hard to say whether this will happen - on the one hand, Apple seems to appreciate that different devices have different functions and needs, and that people expect to be able to install what they want, how they want on their computers. On the other hand, the App Store model has been very successful and lucrative for them, and the company has a history of throwing power users under the bus to appease the masses.

In either case, what we have here today is mostly a net gain, regardless of how you use your computer: existing functionality has been preserved (unless you use Rosetta), some useful new features have been added, and Lion runs as quickly on the same hardware as does Snow Leopard (unless you've got a Core Solo or Duo Mac, in which case it won't run at all). It's another incremental OS X upgrade, and like most OS X upgrades, it's fairly easy to recommend as long as your Mac and your programs support it.

    Okay, it makes sense on a touch device where your finger is actually making contact with the thing you are scrolling. But a mouse cursor is *not* a finger. It is not an analog for a finger. It is a different input paradigm entirely, and trying to make it behave as if the mouse cursor is your finger by making scrolling go backwards is stupid.

    It's good that they put in an option to disable the nonsense that is "natural" scrolling.

    Not at all. The issue is simple : what is the metaphor?
    When I move my finger, am I moving
    - the window container? OR
    - the content?

    Claiming that one is more "natural" than the other is as stupid as claiming that English is more natural than Chinese. It's simply that you are used to one and, like a good American, you simply cannot imagine that the world could possibly be different --- after all, Jesus spoke English.

    Not at all. There is no "finger" when using a mouse. Touch and mouse-driven are distinct input paradigms. If a touch-based interface ever scrolled content in the opposite direction that the user moved their finger, then people would say that it was broken. And rightly so. Moving content in the same direction as the touch is the intuitive operating mode of a touch interface.

    And similarly, moving content in the opposite direction of the scroll (or more accurately, moving the scrollbar in the same direction of the scroll) is the intuitive operating mode for a mouse-driven interface. By your logic scrollbars themselves should also be inverted.

    As a side-note, a direct analog to touch style scrolling does exist in the mouse-driven paradigm, it is the drag operation. It is available in some things like Adobe PDF documents, and also work on any scrollbar. In this operation you choose an anchor-point, and then that anchor point moves in the same direction that you move, and it all makes sense. The problem with scrolling is that it has no anchor point, it is a distinct operation from a drag operation, and by conflating the two Apple has broken their interface. At least until they start incorporating touch into every computer they sell.

    Mouse-driven and touch interfaces are not the same thing, and just because a metaphor makes sense in one does not mean that it also makes sense in the other.

    Agreed.

    On page 23 "Performance: Similar to Snow Leopard", you have a couple bar graphs comparing Snow Leopard to Lion performance. Unfortunately, you use a generic "compared to before as 1.0" metric, with no indication on a per-test basis whether higher or lower is better. In the Core 2 Duo graph, you talk about boot time skyrocketing, and the boot time graph for Lion shows Lion as "about 1.4" of Snow Leopard, yet you also talk about iPhoto having a "greater than 10% increase in performance", where the graph shows "about 1.1" of Snow Leopard. So in one line in the graph, higher is worse, in the other line, higher is better.

    You either need a per-test identifier (Higher is better / Lower is better) or you need to to standardize them all (so 'benchmark' ones would stand as-is, while 'timing' ones would use the inverse, so that both would be 'higher is better', or example.)

    Did anyone check to see whether Apple has included a UI element to enable IPv6 privacy extensions for statelest address autoconfiguration?
    And did DHCPv6 to get IPv6 addresses from your ISP's cable via IPv6 finally make it's entry?
  • Deaffy - Thursday, July 21, 2011 - link

    Oh yeah, and maybe the ability to query a name server via IPv6?

    they are more and more returning to the Linux it came from. Who knows, they might even go bact to open source:-)

    Anand/Andrew/Christian,

    If you right click on a YouTube video, does it say the rendering AND decoding is "accelerated" ? I thought Lion was supposed to bring that.

    If this is now the case, it'd be enough reason for me to buy Lion and a new MBP 15". I can't stand the fans on my 2008 MBP 15 going nuts every time I watch a 30 second YouTube clip. The laptop gets unreasonably hot right now.

    @moids

    P.S. I'm not a fan of the way buttons appear on the upper borders of windows. There's no typical button "design" to signify that the text is clickable, at least not from the screen shots I saw in the article.

    I guess it's disabled:
