Digital cameras both P & S and SLR's have improvement in leaps and bounds over the last few years but even then some features are lacking, still poorly done or maybe overdone. Here is a list of some things that really annoy me and they are not about Nikon only but any brand
Picture Count: You shoot more than 999 pictures on a card on my D300 and the count goes back to 1 and total pics will max at 9999. Why on earth could the count not max at 999999, then for the life off the camera each picture could have a unique number. The picture file should also incl a tag that would link it to the actual camera that shot it, if you have let say 2 D300
Wireless connection to flash etc should move from that annoying short range infrared to radio transmitter
All SLR cameras should have a viewfinder shutter like on the D700 it annoys me to remove the viewfinder cup and put the cap on, I usually end up using my lens cleaning cloth
Stop this annoying MP race, there is simply a balance of MP, noise, lens quality, and honestly higher MP on lots of cameras, special P & S only results in larger files not actually any real gain in picture quality
I would like all cameras to adapt to the same RAW format, what if you have saved your RAW files for a few years and suddenly your files are no longer supported
Batteries, USB cords, long cords on Chargers, Why so many minor changes to batteries and why could not all cameras use MiniUSB connections, just like all cellphones are going to do and why this long power cord for my Nikon charger
Anyway that is all, I think
