Well thanks for wanting to take away *MY CHOICE* to use the OS of my choice.
As to looking nice - yes if that's *ALL* that matters then why not just give WindowsXP a RISC OS theme and have done with it.
Your choice is Style or function - and I'd choose function every time. Having a "rounded" button to me appears somewhat less important than being able to do fast UDMA disk transfers and the like. But unlike you I'd not wish to limit *YOUR* choice - so persist with RO4 if you wish...
