First time Apple product owner here... I purchased a new 27" I5 2.8 ghz and am wondering if what I received is indeed the mid 2010 model. First of all, the date on the box says 2010/06/19, which I take it to be the assembly date - June 19, 2010. Running System Update showed 6 items that needed updating. The iMac came with Safari 4.0.5. The update version is 5.0.1. It also came with OSX v.10.6.3 and the newer version is 10.6.4. The card reader type indicates an SDHC. The mid-2010 model has a type SDXC Did i receive a mid-2010 model?
