Interesting article, albeit pretty unfair to Canon. The author really can't compare the D5K to canon's super zoom point and shoot. that would be like comparing the new 500D (Rebel T-something or other) to Nikons (i think) P90.
I guess the new Canon is still larger than the D40 or D5K, but the article makes it sound like Canon doesn't have a sensor that could even come close to competing with the D5K. If I was in charge of Canon's marketing and PR people, there would be some things being thrown around our office right now!
