Well... coming late to the party, because I have been saving to buy my first iMac. Ordered my iMac a few hours ago. It's currently listed with a 22/03/2013 - 03/04/2013 delivery date. I have been waiting for a year to make this order, so a bit more time won't be too agonizing... may be
I think you are in for a sad awakening!
I had to save up too and that part was bad enough, but the wait after was even worse! I think because I had finally accomplished my goal and was ready to go, but now I have to wait even longer. My card has finally been charged (as of this morning), so I am hoping to have it next week sometime. (Ordered February 6th)
