Pros Improved startup time vs Lion. New stylish dock. AirPlay. New Safari update is over satisfying. Dictation (Siri) works flawlessly! More iCloud integration.
Cons Notification center isn't very useful. Lacks support for capable older hardware. Trackpad use on desktops STILL very buggy.
Summary I am pleased with Mountain lion. Apple did a fine job of refining the dock, Safari, iCloud features, and security features. Mountain lion takes more advantage of Apple hardware, I do believe. I am currently running Mountain lion on a 2011 21.5 inch iMac. I also have it running on a 2009 MacBook Pro. The MacBook Pro, although old, is very capable and should be able to take advantage of AirPlay. On my iMac, airplay works wonderfully. I am still having issues using the trackpad. When in use, sometimes the computer will not pick up clicks. I am on second trackpad. Thus to my conclusion, it is a software error. Although downloading this new operating system was convenient, I still would rather have a DVD copy for backup and restore purposes. In my opinion, the dictation feature is by far the most handy. This entire paragraph, with the exception of a few words here and there that needed correction, has been written using the dictation feature. Although I do not find the notification Center handy or helpful, I do believe with more app integration it will find more use.
When lion was initially released, I was frustrated with Apple because I believe that they took a step in the wrong direction. Compared to an already outdated Snow Leopard, lion was extremely slow and did not take full advantage of Apple hardware. After a few updates, it became more stable and was more pleasing to use. With Mountain lion, I have been pleased the entire time because I have not experienced any problems with the operating system.
Here is my final conclusion: if you want to spend $20 on apps that have been ported from iOS, go-ahead. Snow Leopard and Lion are very capable operating systems and still have a bright future ahead of them. Mountain lion is merely an update.. However, if you own a newer Mac, the features are innovative and handy. Well worth the $20.
Pros Love the new notification and voice dictation features.
Cons Haven't found any yet.
Summary I upgraded the RAM from 4gb to 8 gb right after I upgraded to Lion last year due to my otherwise fast running Macbook Pro running very sluggishly after the upgrade from snow leopard. It still ran slower but acceptable even after the memory upgrade. After the upgrade to Mountain Lion I noticed an immediate improvement on the speed that different programs loaded. It's only been 1 day but the computer seems to be running everything faster. I would recommend Mountain Lion.
Pros Cheap, cool Notification Center, Twitter Integration, Airplay and so many more...
Cons None found yet
Summary Mountain Lion is worth every cent...
Pros Fast, smooth, efficient
Cons No Trailers app in App Store
Summary Mountain Lion's great. Pretty much like Lion, but with a few new features. Notifications is the stand-out difference. But the greatest improvement to me is the overall polish and smoothness. It feels a bit more finished than Lion. Things seem more responsive and behave the way they're intended to. But my gripe in both Lion and Mountain Lion is that Apple took Front Row out of the OS so we can't watch trailers anymore. iOS and Apple TV at least have the official Apple Trailers app, but it's not in the Mac App Store. What gives?
Pros Stable enough on first release. Adds some useful features to people married to the Apple closed garden
Summary This is a OS upgrade for Apple lovers. No not the one's who buy Mac's and stay away from being trapped in a closed Apple garden. I'm talking the ones who havw a Mac,iPhone and iPad and probably 2 or three iPods. Those are the ones who will best benefit from the upgrade of Mountain Lion. For $20 if all of your third party apps support it. I don't see a reason not to upgrade. As it stands the way Apple is going you will be left in the dark if you don't. Apple is all about frequent hardware purchases and killing off what was once the pride of Apple. This is nothing new folks. Apple is not Microsoft. It won't support a OS like Microsoft has done with XP. Nor will it support what it considers older Apple hardware that's obsolete. Don't you feel like buying a Mac is like buying a car. It loses value in Apple's mind the minute the new model comes out.My review is simple because for me Mountain Lion is not anything real special. Its another incremental improvement from Apple that adds some more IOS features and basically caters to a Mac/iPad or iPhone user. If your not into owning lots of Apple products and only own a Mac your not going to find this much more then a Lion refresh.
