haha yaa & where are the haswell iMacs anyways? so haswell processors are going to give you better battery life on new iMacs as well? interesting..yes, i'm sure that apple is going to make Mavericks "haswell only" especially considering the only haswell macs are the new macbook airs. They will obviously abandon all other computers that they make until they are updated.
Not to mention the beta which is working on ivy, sandy, and many other processors. I guess by release they will just go haswell only so that the 5% of mac users with a haswell air can enjoy the new OS!!
