It works when you are wearing gloves, unlike the iPhone where you have to buy special gloves to use it without to get your hands cold.

It can also count calories and while the presentation made it seem like it can be a doctor in your pocket, that majority likely isn't wise.

"At this point, Samsung appears to be trying to kill the competition with sheer volume of new features there should be something here for everyone, if most of these new features won't be used by most users," said Jan Dawson, chief telecom analyst at Ovum, to . "Samsung can most likely rely on its superior marketing budget and the comparatively weak efforts of its competitors in software to keep it ahead. But competitors will catch up and Samsung will have to continue to stretch. In general, there are lots of features, but established on experience majority of people will never find them on the device."

Despite the ridiculously tacky keynote presentation, the new features all seem like stuff that will be useful if at work or our while having fun. The trick for average people will be finding the features.
