I am currently on the latest build of Mac OSX Lion and I STRONGLY believe that Snow Leopard is a better overall operating system. I will be fair and continue to test it until it reaches final but things will not change much as it is a month from release. UI: Buttons - The buttons are now small and harder to push. When you hover over one, all of them show their functions (X, -, +). They do not look right and consistent with the UI. Transition Effects - I understand it is still beta. However, from what I see now, the effects are very poor. For example when emptying the trash, there is a lag for the window to pop up. Finder/iTunes - iTunes 10 was a sneak preview of Lion's new UI. I do not understand why Apple would go from a colorful theme to a black and white one. It is very boring. Also, the shades of grey make it seem like the buttons are sometimes greyed out (inactive), but they actually work. Below, I think it is obvious which looks better. vs. Full Screen Button - Full Screen applications are cool. However, that button really bothers me. I wish it only showed up when you put your mouse over it. It simply makes things look more complication in OSX. Gestures/New Features: Mission Control - The point of Mission Control is to merge Expose and Spaces. However, I have never met anyone that actually uses spaces. Therefore, Mission control wastes space for me to choose applications on my screen. It simply makes it harder. The gesture for it (4 fingers slide up) use to be for hiding all applications. Now if you want to hide them, you have to do an uncomfortable thumb + three fingers up gesture. Sometimes the gesture doesn't work and takes me into Launch Pad. Launch Pad - When you get your Mac for the first time, you have three stacks on your dock. Applications, Documents, and Downloads. Launch Pad makes it harder for you to get to your apps since it is easier to open up a stack. Resume - Resume is actually a cool feature as a backup plan for anything going wrong. However, when most people turn off their computers, they turn if off for a reason. I have to uncheck that I do not want to resume when I shut down every time. I wish there was a way to completely disable it. Versions - Pretty cool I admit. Summary: In all, Lion is just an update to Snow Leopard with an attempt to change the UI for the better. However, it is even more inconsistent than before. Snow Leopard is much nicer in terms of color and design. Lion also includes many features that make things more complicated and less functional (Mission Control). None of these features are really needed for me and many users. I understand this is still in development. But there are no bugs I can tell in Lion, just functionality problems due to the new features. Mac is suppose to be about simplicity, but now it is becoming more complicated and down hill. I hate to say it, but Apple may just be out of ideas. I will be fair and try it again when final comes out, however, if it stays like this I have no problem going back to Snow Leopard. What are your thoughts?
