I was going through the threads and there were many discussions on the topic. But with recent announcement from Intel that they are gonna delay commercial launch of Ivy Bridge processors, is it wise to buy a mac now or wait till late July 2012 ? I don't wanna wait till that time if the performance boosts aren't that much significant. So is it worth waiting or get a mac air as an interim solution. PS: I want (switching from PC to MAC) but don't need one immediately.
