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.

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!Uritziel - Friday, July 22, 2011 - link
None of that sounds wow worthy...Uritziel - Friday, July 22, 2011 - link

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.
