I am an amateur beginner photographer. I had been musing on buying a Nikon D90 'for the advanced'. I have a Nikon D40X. But as I read those books on photography like for example, Ansel Adams THE NEGATIVE and THE PRINT and so many many more educational books like wedding, pet, landscape photography, I felt that I have to learn more from these authors. So I am need not be in a hurry to buy expensive cameras suited for the advanced until I leave the beginner's class.(as advice from a professional photographer. Besides, prices might go down in the future because of stiff competition. At present, I have been enjoying reading every book I can get hold of. I just love photography!
