Hi, Just wondering if the Jan 2009 or 'early 09' models have the same freezing/beachball issues the 'late 2009' models have? I've had 3x15"MBPs and 1x17" MBPs (all June 2009) that had the freezing/SATA issues so I'm keen to avoid these problems. The Refurb Store has a Jan 09 model that is calling out to me! Can anyone confirm that I won't have any SATA issues with this model? Will I easily be able to swap out the HDD without any compatibility issues? Thanks.
