If you're having a problem with being unable to see clearly during your webcam conversations, the Logitech C615 might be worth the purchase.
The Logitech C615 will actually let you shoot images and have face-to-face Skype conversations in 720P high definition. So, even if you do a closeup shot of your face, the quality of the image won't decrease. There's a built-in mic that eliminates background noise so that your video calls don't get spoiled. In addition to these features, you can also take software-enhanced 8-megapixel images.
Mac and PC fans won't have to fight for this one as the Logitech C615 is compatible with both systems. Look for this to be released sometime this month.
