I e-mailed Apple over the weekend regarding the estimated delivery date for my order, as it doesn't provide this when I check the status of my order (I know, I'm impatient)
They got back to me today - they didn't really give me an answer regarding the estimated delivery date, but they did say "Apple expects to ship your order on time". My estimated shipping date is Feb. 24th. That is a little reassuring - I hope it ships earlier :P
When I ordered my Mac Mini last March, it was supposed to ship on April 8th, but it got pushed back until April ... 21 i think? Sucked that I had to wait longer, but it worked in my favour, as I qualified for the Tiger Up-to-Date. Had it shipped on April 8th before the official announcement of Tiger (on April 12th), I wouldn't have qualified. I know its hard waiting, but sometimes good things are worth waiting for :P
