It seems that a lot of people are worried about no internal superdrive. It is NOT a DEAL BREAKER!!! For those who don't know or aren't sure, it's absolutely simple to connect a USB superdrive from any number of makers to your imac via... USB. It acts exactly the same as an internal except it's external. They start from around 40bucks (and you could get them even cheaper online). I have a 44buck LG and it works fine with my 2008 imac. Hope this helps.
