I just don't get it. Apple announced a brand new iMac in an event held on October 23. Since then, it stopped selling the old iMac on its online store. The new 21.5" iMac will be available in November (we're on November 4, and it still not yet available) and the 27" iMac will only be available in December. Why didn't Apple just held another event on December to announce the new iMac so it would be immediately available after the announcement? Are sales of iMacs so low that Apple can handle staying so long without selling these machines? Does that make any sense from a business perspective? Am I losing something?
