Just to be contrary... I would somewhat disagree. I don't know anything about the 600, I went for the 800 before it came out, but I'm not sure I would necessarily say the 7000 is a fantastic camera and all anyone needs. While it does have an expressive specs for the $ equation, and CAN perform very well under many circumstances, it also has some limitations that can be crippling in others. Such as AF that struggles with moving subjects in lower light levels, and mirror slap induced motion blur at key shutter speeds. Whether or not the 7100 has addressed these or not, and depending on risk tolerance for moire, it may or may not be an important upgrade for someone.
