OSX 10.7 finally ditched Rosetta support and installation footprint became smaller then OSX 10.6 (i still run it) All the iOS like "social features" have 0 value for me, but i'm interested as it performs as "operating system" - meaning supportive environment to run my creative applications: Adobe CS6 Master Collection, Final Cut Studio, and all other application. Multitasking behavior, boot time etc. I know we are not getting any new file system apple promised years ago and then ditched. How does it manage RAM? Does it have less demands itself allowing my apps to run most efficient etc. ? Few features i like: Safari version that caught up (finally) with the other browsers (google chrome like search bar) and dictations. Anyone has info regarding such performance improvements ?
