Howard, I agree on all points. By pure accident I bought the D300 on 10 Dec 2007. Walked into a small branch of Wolfes in Houston ,Tx, to buy a lenspen.... asked the manager if they had seen the D300 yet and they had rec'd 20 the day before. One of the pre-orders had not shown up to collect after several phone conversations and the manager was not happy....so.... Fortunately I only suffered from DBS once and the roving focus point but both were fixed with firmware.
My present thinking is that I will ask the Mumbai dealer when they expect another shipment. This is not due to the AF points issue but along you idea of letting the camera get "Tweaked" in general.
I did see all of Ming's post and blog comments. Funny, I would not have tested as such but would have been very upset shooting birds and having my 'composed' shot oof because I was using an outer point! I have high hopes for the new f8 AF since I've recently been shooting D300s/500vr/tc1.7 in very low morning light and had to move down to f7.1 from center point to get AF.
