We could add what software we actually bought!

Most used:
VBCC and SASC (for it's debugger), WHDLoad, Amplifier and SongPlayer1.53 (for some eqing on treble / bass adjustment wich is available on others for PPC only)
Favorite:
ImageFX4.5, DPaintIV/V, WHDLoad. Brilliance. CubicIDE is very good even compared to other platforms but I'm too used to a standard editor and command line.
Software I bought:
IFX4.5, Cubic IDE, Wordwordth7.1 (sadly doesn't support 24bit pics), WHDLoad, AOS3.9(!

, TZero (very good and enjoyable actually but got bored...), Myst.
