I ordered mine on Monday, also with the educational discount. According to someone I spoke to at Apple, you will get your's earlier if you buy it over the phone, rather than online, as the telesales dept. have priority. It was dispatched on Thursday and should be with me by Monday.
All in all it was a bargain with the student discount. I'm gonna swap out the stock HDD for a 160GB model. It was gonna work out cheaper to do this upgrade myself rather than get apple to do it for me. I did get them to put in the 2GB RAM tho.
Nice little early Christmas pressie to myself. Now all I have to do is work out how I'm gonna get a tri-boot setup with Linux and Windows on the go!
