gulli: No, but then I wouldn't really want to use them at all. Using RO 3.1 is almost no difference to use RISC OS 5 in look and feel. Once it has a nice set of toolsprites and a decent desktop font set. Using VA5000 on a decent spec system is not a step down from using the same apps on an Iyonix in the same screen mode.
The step down is the programs that won't run and lack of memory and screen colours.
A fairer comparison would be using OS X 10.0 to advertise 10.5.
