I voted "yes":
Consider that OS3.x can run, under emulation on fast x86 hardware at speeds far in excess of any real m68k used presently in any existing Amiga. If we consider UAE/OS3.x with RTG as a platform, it has ample CPU and 2D graphics performance to cope with more "modern" apps. It's also probable that there are more instances of this platform than there are physical Amigas running OS3.x, and as they slowly suffer the attrition effects of old age, that ration will probably increase.
