Just wondering if anyone has taken the plunge on the new Canon Rebel T4i. I currently have a Canon XSi, and am considering upgrading to the T4i. I like the idea of being able to shoot video since I frequently have my DSLR with me but not my video camera. I've also considered getting the T3i instead since it's on sale at a lot of places now. For those of you who have bought the T4i, what do you think?
