I switched to mac almost more than a year ago, one thing Windows vista has over mac, is the option to control which application can have audio. This is very useful as when you are listening to your music on itunes while navigating safari, the annouying ads start suddenyl playing and disturbing. In VISTA AND 7, you can trun off the audio for lets say firefox. However this is not possible in mac.. Honestly, I sometimes think that windows has a lot more features than mac.. Im afraid that apple is working on too many products and has lost its focus on quality... whatever. does anybody agree with me on this useful feature and how can we ask apple to incorporate it?
