IMHO, there's still "need" for AmigaOS software, as some people use an Amiga/Amiga clone (be it an AmigaOne, a Pegasos or perhaps even a Sam or a 68k one, I don't know for AROS) as their primary computer. For some of them native PPC/x86 sw is preferred, but since OS4 and Mos have built-in 68k emulation, 68k software would be also welcome: e.g. AmiGift or HDRec.
What I'd need lately is a video editing software, a Flash plugin (both are under development anyway), a version of Lha which correctly handles archives with thousands of files (both OS4 and 68k versions have problems, at least under OS4, while LZX seems to work fine), and drivers and a simple application for USB webcams.
