BTO is built to order. so any added hi-res screens, 7200 hard drive, or other custom options. I guess they would take longer.
Mine still just says "Shipment Dispatched"... theres no tracking number or courier details yet... urgh, I am so impatient!
Ah, I got the base 15" i5. Only thing I added was the hi-res glossy screen.

Thats how mine currently looks.
Hopefully yours gets more details soon :/
