Agreed. Trying to "close options" off on people is a bit shortsighted (a bit too much stick and not enough carrot). The more positive approach of stating that the software works better on/runs faster on/can do more on "X" rather than legacy kit should move people forward.
The other side of the coin though has this *really* worked? Many people still use RPCs (some haven't even upgraded to the StrongARM). And bear in mind SA gave an x5 improvement in performance (surely enough of an excuse)
The real kicker is that software can be *limited* by the hardware it runs on - and that often means more imaginative/flashey type applications doesn't get written and then people can't see a point in upgrading their hardware (a sort of vicious circle).
I'd agree with you also that there may be many "small" utilities and applications that *could* be resurrected to run on 32bit hardware some as free/shareware others as commercial products.
