After a bit of a hiccup requiring a restart and PRAM reset, it appears that 10.7.2. manages system usage and RAM usage a lot better than 10.7.1. Often when I was running Safari and Pages I was seeing available free RAM of less than 100MB at times, now its often over 1.4GB free. Also noticed that tabs actually close in safari when the X is clicked, full screen taskbars function, and a slight decrease in start up/shut down time. For now there also appears to be a snappiness to the UI with less beach balls of death than before. But time will tell.
