John.P and Martin.W are right; that's the point I was trying to make. As Intel are working on a family of CPUs that use IA32 (aka x86), and making them suitable for consumer device use, it's been suggested that this move will marginalise the XScale to just mobile and other specialist focused devices - but if that's where ROS is heading, then it's ok. I'm not sure where ROS is heading, though.
I could be wrong, so feel free to correct me, if so. I'll be interested to hear.
