<human>: Summarize the given text in a few sentences.

I have been wanting to purchase a new point & shoot camera for a while, and the GoPro cameras have piqued my interest. A friend of mine just got one, and I am quite impressed with the still images it is able to take, let alone the videos. I think that buying a GoPro or similar camera is what I would like, but I don't know much about the market for these types of cameras. Are there others that are major players as well, and if so, what would make anything a more attractive choice than the GoPro brand? 

Second, I am wondering if anyone who is more familiar with these cameras has any insight on whether or not I should wait for an upcoming product to be released rather than purchase one now. I realize that technology is constantly improving, and that there will more than likely be something at least a bit better in short order. I am asking if there is a product due to release soon (before May) that will be A LOT better than the current technology. 

Thanks for any help you can provide!
<bot>: Should I buy the GoPro HD Hero2, or is there a better choice? Follow up- Is now the time to buy or is someone about to release something far better?
