What is your "kit"? What do you want to add in the future?

My kit is as follows:

Nikon D200
Nikon 18-70 DX
Nikon 70-300 VR
Nikon 10-24 DX
Nikon 105 Micro VR
Nikon 35 1.8 DX
Nikon SB700 Flash

Bogen 3001 Tripod

Honestly, I am very happy and feel no need to "upgrade" unless that includes upgrading the ability of the photographer

I think my biggest problem is that I use iPhoto as my primary sorting and editing software. My computer is fine but I need to learn the "digital darkroom" in the near future.
