Dear All...

Just wonder..Does Apple always announce new models with delay shipment, like Mac Mini with 3~5 weeks delay?
Don't like to see it on iMac after announcement...

Thanks.
Best Wishes.

Mac Mini ships in 24 hours http://store.apple.com/us/browse/home/shop_mac/family/mac_mini?mco=MTAyNTQzNTk

Usually they ship in 24 hours or in couple business days after the update
