> Why are we sticking (even RO) still to 2 dimensional WIMP interfaces based on 20 year old technology.
Because we have 2d input and output devices still.
The portable computer you carry around now, be in mobile phone, pda or laptop will end up being your only computer, connecting to larger IO devices that are available where you travel, so they're eventually become as powerful as desktop computers.
If you want more power now work out how to use multiple CPUs with RISC OS.
It's easier to convert VRPC to another platform than RISC OS, so it's less tied to Windows than RISC OS is to ARM.
If you can't access RISC OS websites from none RISC OS machines how do you expect to gain customers? Just make it slightly annoying, a bar across the top that says IE is bad because... But you need a realistic alternative, so support attempts to get lots of software running on RISC OS.
