The cameras/lenses and software now available are, in many cases, way beyond the capabilities, training and talent of most photographers purchasing them. I say this as someone that can be included in that group and that was weened on 120mm and 35mm film with a variety of cameras (Kodak, Rollei, Minolta, Olympus, Nikon, Canon and now both Nikon and Canon DSLRs). The capabilities of digital are outstanding and I can say I have improved the most since I bought my first Nikon digital and moved through to where I am today. The greatest opportunities today lie in being able to experiment at little or no additional cost and to easily do "darkroom" work that would have required tens of years of experience and an incredible time commitment in the past. With the proper feedback and some dedication you can produce work that was only possible to professionals. That said, much of what is shared here as information, facts or analysis is really just polished forms of emotions run wild or fears writ large. Even if you have an investment in a lot of equipment nothing Canon has done recently will ruin you or humiliate you personally or professionally. Only the most anal among will be forced to change to Nikon because Canon was just inadequate. They may choose for some feature(s) that they want but rarely is it because they just can't do their work.
This constant attacking of Canon is somewhat sad and I agree heartily with briansquibb. The Canon product line reflects where they want to develop the business of still and video photography. The cameras/lenses we have to choose from are outstanding and although not the very best in every dimension, measurement or price they are quite competitive and produce great results. We are not made to buy or be loyal but can choose to do so if the value proposition is right. We can choose otherwise without attacking the firm, their integrity or intelligence. They are very successful by any means (just look at the sidelines at any pro sporting event or just walk the streets of any world city to see). From point and shoots of every shape and color to the forthcoming Canon EOS-1D X it is an amazing series of products for every skill set.
I owned a Nikon DSLR kit and now I shoot with Canon. I was happy then and I am happy now. I spend my energy learning away to get better every time I go out and, hopefully, to do the equipment I own justice.
