Should I Get the iPhone 4?

Bringing back my more vlog style of videos, I got the call from Bell today, and my iPhone 4 is in stock and ready to be purchased. Only problem is, because I have only had my 3GS for less than a year, I will have to buy the iPhone 4 full out on no contract. In the end, it will wind up being somewhere around $750-800 dollars. So here is my question, do YOU think it is worth it to upgrade? Let me know in the comments section below.
