To the fact people are mentioning Apple wouldn't send things surface, that they always air freight new products; think about it, even when you air freight mass quantity is costs a ton!
Apple just settled a lawsuit, it costs them what, maybe a buck a unit?
We bring in IP phones in my business, they are about 4 times the size of an iPod.
We pay about $13 to air freight in bulk, but only $2 to send them by surface.
If Apple is still ironing out content negotiations, but has already completed the design and has gone into manufacturing, take the slow boat from China! They save the money they lost on the lawsuit in no time, have plenty on the day they chose to announce, and its a win for everyone other than Fedex.
Don't put it past them; with the delays focusing more on the content providers, Apple can finally take advantage of shipping ahead of time.
