Back to the Mac: OS X 10.7 Lion Review
by Andrew Cunningham, Kristian Vättö & Anand Lal Shimpi on July 20, 2011 8:30 AM ESTApple introduced the Mac App Store (MAS) in its Back To The Mac event last October. It was released to public on January 6th and was automatically included in the 10.6.6 update. It’s obvious that the MAS is a spinoff of Apple’s extremely popular iOS App Store. While the MAS has been available for over six months now, Lion will bring some healthy improvements.
First, there will be support for in-app purchases. Since Apple does not allow trials, this is mainly useful for applications that can have additional commercial features or are subscription based.
Second, developers can now send push notifications to alert users. As in iOS, the usefulness of this feature varies from app to app, but the presence of third-party plugins like Growl speaks to the demand for this sort of thing.
Third, app updates are now just patches instead of full copies of the app. Apple refers to these as "delta updates," which is the traditional development term for an update delivered by replacing only the changed files/bytes in a application. In Snow Leopard and in iOS, you had to re-download the whole application to update it. That was very inefficient, especially if you were updating a bigger app. After iOS 5 comes out this fall, both it and OS X will feature app updates via patches, just like most other programs have been doing forever.
On a technical note, the structure of OS X application bundles makes them fairly well suited to these kinds of updates. But it's not clear at this time whether Apple is replacing whole files or doing binary patching to minimize the update size. Valve’s Steam service recently transitioned from doing file replacement to binary patching for this very reason, as games typically use a handful of large archives to store their content. For regular applications the difference is subtle, but the difference will have an impact on games distributed through the MAS.

Well, since Apple retains 30% of the App price, I'm not sure if that figure above is talking about the total amount that customers have spent buying songs and apps, or if that's Apple's revenue (ie: 30% cut) of the pie.PreOmegaZero - Wednesday, July 20, 2011 - link
Microsoft names the OS versions as such (6.0 vs 6.1) because changing it to 7.0 (like they admit they should have done) broke many older apps/installers that did OS version detection.So the version numbering is simply from a compatibility standpoint.

These aren't service packs. Its a silly comment which tells us you either don't know what a service pack (which is a Microsoft term for Microsoft software) actually contains or you didn't read this review.Belard - Thursday, July 21, 2011 - link
Service packs? Apple uses actual version numbers, but in the past few years - they've only been patching Snow Leopard.The difference in XP SP1 / SP2 / SP3 is bug fixes, security patches and a few things here and there, but feature wise, no difference. XP-Home/Pro are visually different than XP-MCE (Which is XP Pro with a nice visual face lift but with VPN ripped out).
I think Apple charges like $50 for a 5 user license upgrade... much better than the lame Win7 (Vista and XP) charging $100 for an upgrade disk which is messy when it comes to a clean install.

"much better than the lame Win7 (Vista and XP) charging $100 for an upgrade disk which is messy when it comes to a clean install."You have no clue about which you speak. Win7 upgrades/clean installs are simple for even the simplest minds-present party excluded apparently.

An improvement? Uhh, you are aware that Snow Leopard ALSO sold for $29?The more interesting points you should be making are that:
- $29 gets you the right to install the OS on EVERY mac you own. It's right there in the TOS. For most people this won't matter much, but for those with a desktop machine, a laptop and a HTPC, it's rather cool.
- and you get the right to virtualize two instances, if you care
- and note the conspicuous absence of any sort of DRM covering the OS, not to mention the home/home mini/pro/ real pro/enterprise/super singing & dancing version crap that MS offers up.
(And, BTW, you get the Dev Tools for free. They were $5 in SL, but I think they've dropped to $0 with Lion.
As far as I know, Dev Studio is not free, not close.)

Assuming that by "Dev Studio" you mean "Microsoft Visual Studio", yes, they have a fully-functional free version.name99 - Thursday, July 21, 2011 - link
How come when I go tohttp://www.microsoftstore.com/store/msstore/en_US/...
I see a bunch of different prices, from $3,800 to $400, but no $0?
I'm not being pissy, I really want to understand what is going on here.

How can you buy something that's free?http://www.microsoft.com/visualstudio/en-us/produc...
