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 is giving you a chance to wipe the slate clean after launching its air-sniffing flagship, the Smart 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 / €150 from today, just don't forget to cancel the In-N-Out order on your way to the store.
