It’s been something of a long week, especially for those trotting around in the Las Vegas desert for the 2012 International Consumer Electronics Show, which wraps up today. As we sit back and reflect on the week’s events, let’s take in a few more tidbits of news from the last 24 hours, including the troubled launch of the iPhone 4S in mainland China, kudos for Tiffen at CES, Apple’s supplier responsibility report and more for this fine Friday, January 13, 2012. Watch out for those ladders and black cats, folks!
