My first post in these forums will be in the form of a rant. Apologies ahead of time
This "I'm going to switch because so and so created a better camera..." line frustrates me every time I read it. Do you really have a need for a 36 megapixel camera, or is that just for bragging rights? I think the majority of people who say things like this have invested very little into photography, lenses and learning their current system. My 5DII & 7D have more than enough megapixels, excellent low light capabilities,are easy to use cameras that help me get the photos I want. Hell, I still use a 6 megapixel Pentax K110D which produces great results. And get this, I often shoot with a 50 year old Voigtlander which also does a great job. And complaining that there is no IS on the 24-70 is ridiculous. Why do you need it at a relatively short zoom range? It is not needed in my opinion. I've also read from so many that Canon should put IS on all primes! That is laughable.
Granted, there are plenty of people with knee jerk reactions and too much $ to spend. However, I
get really frustrated by people who use the logic of "my camera works great for me, so why should you need anything different?"
I was reading up on the D800 this morning and have to admit I'm tempted. I think it would show a concrete improvement to my (albiet limited) photography income. But this is due to my style, my subjects, and my clients. I don't expect everyone (or anyone, for that matter) to have the same needs as me, so if other bodies or lenses are what they need, great, I'm not going to put them down or question their intellect.
Of course switching to "the dark side" would mean I no longer have use of my wife's $10k lens collection, so I'm going to have to consider pretty carefully!
