看了这篇 “What happens after you’re arrested at a protest in New York ”，其中讲到作者被纽约警察逮捕之后的一则插曲：

Technology side-story: My phone was confiscated, but it was being held nearby. I was wearing an Apple Watch for product testing, and was able to send Lian a text message over the watch (the whole time we were held I was not allowed a phone call or any contact otherwise). I somehow doubt that this particular use case is one that Apple will promote, but it was the most compelling one I’ve found so far…

这是苹果手表的一个用例：你被抓了，虽然手机被没收了但就在附近，这时候你还可以利用iWatch联系外界。这可能是iWatch最赞的用例了！
