The concept is that we take up too much time and brain space with equipment matters relative to the benefits achieved. Yes, being a geek can be fun, but it doesn't make you a better photographer if you neglect the artistic skills. One can start blaming lack of planning or poor execution of photo plan on outdated equipment instead of one's own bad habits. Truth to tell, my 4 year old digital beginner's DSLR Canon 60D is a miracle of engineering that enables me to do things that I never dreamed of in my film-shooting days. I have a ton of fun with the camera, and as I am not trying to sell huge prints, careful technique and a decent tripod will do very well.
Yes, I am considering getting the upcoming Canon action APS-C DSLR ("7D2"), and the prospect is occupying way too much brain space at the moment. What will this get me? Faster frame rate and better AF relative to the 60D, presumably resulting in a higher "keeper" rate - but it won't improve my ability to find the birds and position myself to get good light and a clear view of the birds.
