A parallel between three Apple devices reveals the differences in weight.
A Cult of Mac article details the differences that exist between the previous two generations of the iPod Touch and the new iPhone.
Three photos show the iDevices placed on a scale.
The previous generation iPod Touch, shown in the center picture, is the lightest of the three, weighing 101 grams.
The one on the left is the third-gen Touch, weighing in at 106 grams.
The iPhone 5 turns out to be the heaviest, at 111 grams, but that’s only 10% heavier than the iPod, which is barely noticeable.
The site writes that because the new iPhone is slightly taller and thicker, it feels lighter that the denser iPod Touch when held.
By contrast, the article notes that the iPhone 4S officially weighs 140 grams.
