Apple 大可以在電路板上額外加進其他有這個功能的晶片組做整合 你這吹牛不打草稿的貨色, 等你把問題研究清楚, 解決了再說吧.

bigandy: really, why why why? iPod has worldwide appeal.
XM Radio is US (and canada?) only. (XM 收音機只有美國, 或許包括加拿大才能收到信號) Anything with XM on board would be pointless on something sold worldwide. (當對全世界銷售時, 任何帶有 XM 功能的電器將會變得毫無意義.)
and if there was a US only one with XM, why would they do it? their costs would go up, they'd have to re-engineer the iPod (try and find space to put in another chip)

if you're talking an XM addon, maybe a little better, but i don't reckon that apple are going to go for something that will work in one market and one market only.

iMeowbot: the one thing I've noticed with all the handheld XM receivers is that they include these big blocky external antennas, (手持式 XM 接收機附帶笨重的天線)which seems to be a big hint that the built-in ones aren't very good. (似乎暗示著內藏式天線接收不是很好) If the radio attachment ended up larger than the iPod itself, would people really want it? (如果 XM 收音機部分變得比 iPod 本身還大, 人們是否真的會想買它? )

dragonsgames : They (Apple) will make money of the hardware, and XM will get the subscription money. It will all even out.
蘋果賺硬體的錢, XM 收到訂戶的月費.
(P.S. XM 不是免費的訊號, 必須付訂費才能啟動解碼器)
