Apple's not forgetting about Safari with all the changes to OS X Yosemite. The browser has been completely overhauled with power-saving tweaks, new tabs and a privacy mode, among other new features. By far the biggest change, though, is in the UI -- it's got a new flat look that matches the new OS. On top of eliminating the favorites bar (which now pops up when you type in the address field), you get a bird's-eye view of tabs, and can scroll from side to side to select them. There's also a new Spotlight search that gives additional suggestions, as well as those from search engines like Google. Apple also says its latest Safari is standards-compliant and no longer requires video plugins for premium services like Netflix's HTML5 player -- which could net you up to two more hours of battery life when playing video.
