I have the 2nd gen Macbook Air (13" 128gb/4GB) and have not yet seen the need to upgrade to Lion. The current OS does everything that I need my computer to do. All I use the computer is for email, web browser, skype and MS Office. Just wondering if anybody else is in the same boat? Is there really a compelling reason to upgrade to Lion? What am I really missing out on? Will Apple still continue to push updates for the Snow Leopard even into the future? At some point will it stop supporting that OS completely? This is my first Apple computer, so bear with me.
