The MBA is my first Mac. I love it. To the point I wanted it to replace my Windows PC machine. I have bought a Mini Display to DVI port and hooked it up to my 24" HP monitor. Finally a zen experience by using a computer. No sound of spinning fans nor working hard drive. Clamshell mode. So unique to Mac. Working perfectly. This is it! I though for a minute. Or two. Just browsing (no Flash or anything heavy) and doing some text editing. Then the fans started to kick in. Louder and louder. And never stopped. I even turned off the browser and only a plain text editor remained. No help. It's the clamshell mode itself. End of Zen. Switch to PC again (it's more silent the the Air with fans running wild). Is this normal? This is how it supposed to work? Approved by Steve Jobs the Zen master perfectionist? Or is it just me? And a second question. Is it possible to switch easily (like with CMD+Tab) between more windows opened in the same application (like two Google Chrome windows or more projects in a text editor)? I am so used to this from Windows and quite frustrated that it doesn't work in the Lion. Any workaround around this?
