MacOS X Lion (10.7) Quick Review

I finally had a chance to try out the latest operating system for the Mac laptop (such as MacBook Pro, MacBook Air) and computers (iMac) called  "Lion".  As a happy user of Snow Leopard and Windows 7 (virtualized via Parallels 5), I wanted to see what the fuss on Lion was about.  Lion was released on July 20th, 2011.

Touted as a major improvement to the previous version called "Snow Leopard", here are my quick findings of visible upgrades.

   1. Ability to expand a program such that take it occupies the entire screen- the way applications do on an iPhone or iPad

   2. "Mission Control" allows the user to see all programs that are running.

   3. "Launch Pad"  allows the user to view all installed applications. Very similar in experience to using an iPhone/iPad/iPod.  that have been installed in one view. Prior to Launch Pad, users either had to find programs via the "Dock" or use the "Finder". Very cumbersome and a welcomed feature. Mission Control looks just like the home screen on an iPhone or iPad.

  

My question is : I use an iMac, so I don't have a touch pad for gesturing. Am I left out?
