So, I was looking at KR's updates, and I read that the D90 can only connect via PTP over USB and that there is no option to use the widely-standardized and accepted MSC (mass storage class) protocol! I have enough junk on my PC already that I don't want to futz around with more software, especially unnecessary software. What's even dumber about this is that it took a deliberate move by Nikon to remove this, because all of their other cameras connect using USB MSC, so they already have the programming for it. This wasn't merely something Nikon omitted, it's something they had to make a deliberate decision and action to remove. Since there already is USB connectivity, putting that functionality back would require only a simple firmware update. So, what gives?
