If using Windows trains you better for the outside world how come everyone I know who uses RISC OS is better at using Windows than 90% of Windows users?
PCs need more knowledge to support, but finding a RISC OS technician could be tricky. Acorn/Castle have the same advantage as Apple, they make the hardware and the software so it tends to work better. Of course that's why they're more expensive.
All these "little utilities" for managing RISC OS networks need collating into a free system.
