Sorry for the Title. Couldnt ally think up of what to write. Do you think that the D40 is one such device which has been made very well and an upgrade would most probably be a practical downgrade? As is the practice of big companies. An upgrade would include just a lil improvement like more AF points, or more pixels (LOL) etc. One such device that I can point to is the Panasonic Gs400 camcorder. Also some of the early P/S cameras with low pixels.
