There are few tech journos whose views and reviews I trust more than Andy Ihnatko. After his year or so wearing Androidwear he’s convinced smart watches are a useful thing, and he’s pretty practical with his recommendations. It’s hard to know how much the thing costs to make but IMO $350 US is an obscene rip-off, especially considering you’ve already given them cash for an iphone.
The Applewatch is a non-starter for me because I don’t nor have I plans to own any ithings and there’s no way Apple will open their watch up to Android.
