I had the first, Canon Rebel T1i, and I rocked it. It served me very well for my first year of photography business
all the photos except the 2 most recent newborn sessions and a few of the timeline photos, are taken with my Canon T1i, So I can imagine that the T4i is even better than that camera!

Now I have a much much needed upgrade to the Canon 6D
