After reading all your posts, I think I can make this final(?) conclusion:
Both the dive-and-drive and the constant descent rate NPA have their loyal fans, although we can all see the later one is quickly becoming the standard with most airlines all over the world.
The reason for this IMHO is that it is slightly safer(?), more comfortable (pax) and very similar (crew) to the regular ILS approach. However, I think the breakthrough of the stabilised NPA came with the introduction of FMS, INS, EFIS and all other modern stuff in the flightdeck, which allows us to calculate and follow up our descent path easily and accurately...
Those guys still using the good old dive-and-drive technique against all odds are of course intitled to doing so, but they should understand that their technique is considered non-standard, even somewhat old-fashioned and that many big companies around the globe will not really like them to use it. In fact it even goes so far that at least one airplane manufacturer (Airbus) more or less forbids their technique althogether!
However, as long as these guys (and girls of course...) keep on flying those good old B727, 737-200 or DC-9 for companies who have no state of the art planes in their fleet, changes are that the dive and drive techinique will be around for at least a few more years...
