Nobody wants to own an unreliable piece of expensive hardware. Who has experienced the ERR message problems with your Nikon D90 here? I love to own a D90 but it appears inevitable that many people experience the dreaded ERR message. I don't want to spend $900+ on a piece of unreliable hardware for which the manufacturer doesn't even admit the problem??? I am in the market for a SLR, and D90 seems to be a right camera for me if it functions without problems, but I wouldn't even touch it with a ten-foot pole hoping I would get a copy without the ERR problem by a sheer luck as purchasing. I'm not willing to take a chace like that. It really sucks because D90 otherwise seems to be a great camera. Could you share your experience with the ERR problem? I really believe the D90 has a design flaw. Nikon really should fix the problem, or maybe the release of D5000 is Nikon's attempt to fix the D90 problem (ie releasing D5000 as a revised D90 regarding the ERR issues)? I wonder if D5000 gets the same ERR issue as in D90? I'm hoping people here could convince me that there is nothing wrong with D90, so I could comfortably purchase a D90 because I don't want to pay for a D300S. If I buy a D90, then start getting the ERR message, then I'm really gonna go crazy. Thank you.
