HTC is offering a rather hefty discount on the little camera, bringing the price down to $50. If you ever considered purchasing one then this should be a good enough reason for you to make the jump. But if it didn't quite convince you the first time around, it's unlikely to change your mind now.
It has no display and not much of an interface. You interact with the couple of buttons on the device, one of them being the large shutter button on top. The RE is meant for spontaneous shots and not really for those who like to compose and setup their shots before capturing.
The camera pairs with your phone to transfer images and you can use your phone as a viewfinder at a pinch but it would just be easier to shoot with your phone, not to mention the RE image quality isn't exactly great. If all of that seems good to you somehow, then it's available at the lowest price so far.
