Flibble: thanks for the informative reply.
Guestx: so why use RO at all? Answer, because it's still more pleasant to use than other OSes, and apps like Artworks and Ovation Pro offer enough power and unrivalled intuitiveness. Also, enough has been done by the small army of mostly volunteer coders and porters to provide improved functionality in vital areas like web browsing (Firefox, Netsurf), common file format reading and creating (GView, JClean, SwiftJPEG), and cross platform compatibility (ViewXLS) to keep RO usable on a daily basis. Thirdly, RO is mercifully free from the remorseless round of security maintenance that afflicts Windows users.
