Just now, I just came back from the shop with my new gear, D90. It just like you are having a second car in your family. More attention and more buttons must be recognized.
I think, I am bit lucky because, before this (while using D3000), I normally trained myself to use the Manual buttons. So that, I can get myself ready for the next advance gear.
Well, this time I hope I can produce much better photos with quality performance.
Thank you D3000, you are always my first DSLR camera...
