AirDrop is a feature which is supposed to simplify file sharing. Located on the left hand side of the Finder window, AirDrop allows you to send files wirelessly between two Macs running Lion. AirDrop's killer feature is that it uses a peer-to-peer WiFi connection between the computers so the computers don’t have to be on the same network, or on a network at all (ed: this is also faster since WiFi is a shared medium; router retransmissions halve effective bandwidth). AirDrop doesn’t require any configuration either, it should just work.

Using AirDrop is extremely easy. You must simply have the AirDrop window open and be within range, and your Mac will be discoverable by other Macs. Once your Mac spots another Mac, you can drag a file on top of the other Mac’s icon in AirDrop window and it will ask for your confirmation to send it. Click send and the receiver will be given an option to either save and open, decline or just save it. Files downloaded through AirDrop will be saved into your downloads folder.

AirDrop transfers are encrypted using TLS and AirDrop also creates a firewall between the sender and the receiver, so using AirDrop should be safe. You will only be visible to other Macs when the AirDrop window is open, there is no need to worry about getting random file transfer propositions when using your Mac in public. You can also verify the sender’s identity through his Apple ID.

AirDrop is a super convenient way to send files when you're physically near the recipient. There are still better options for moving tons of files between unmanned computers, and you'll need to rely on 3rd party solutions for sending files across long distances but AirDrop does offer an advantage in this specific case.

    $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. Reply

    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. Reply

    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. Reply

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

    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?

    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.
