I ordered a (Penryn) Macbook Pro recently and it is now on backorder as expected. In addition to the order, I purchased the parallel desktop software (considering it was free with rebates). I recieved the software yesterday and was wondering if I should wait until the Macbook Pro ships before I send for my rebate on the parallel software since such rebates are pending on the system purchase? Has anyone had experience with this in the past? It would be a no brainer to wait for the system shipment, but the software's rebate deadlines make me urgent to send for the rebates as soon as possible. Does anyone have a guess as to when the Macbook pro's will be in stock and shipping at macmall (or any retailer aside from apple stores)?
