New iMacs in March
As far as we know, Apple pushes out a refreshed iMac every 8 months and a major update every 27 months. The last major update was in October 2009 and the last refresh was in July 2010. So, the iMac lineup is due for a refresh this March. The update will up-to-date the iMac, prepare it for Mac OS X Lion. Moreover, Apple is expected to start bringing the MacBook Air Solid State Drive (SSD) modules to the rest of the Mac family, will add the new Intel’s microarchitecture Sandy bridge to improve graphics and resolution on the 21.5" and 27" displays. Adding this option to the iMacs will improve the readability. Perhaps, Apple will also add an anti-glare option to their iMac display offerings. This will be a minor update, with a major one expected sometime around January 2012.
