We wouldn't blame you if, three months into 2013, you'd let those New Year's resolutions slide a bit. Luckily for you, Withings (http://www.engadget.com/2012/12/11/withings-ws-30-hands-on/) is giving you a chance to wipe the slate clean after launching its air-sniffing flagship, the Smart Body Analyzer (http://www.engadget.com/2013/01/06/withings-body-analyzer/). As well as monitoring your weight and body fat, the new hardware measures the local atmosphere and your heart rate -- to ensure you're not overdosing on carbon dioxide. It's available for $150 /
