There is absolute no advantages for me , as an Omega user , to use either 3.7 or 5. For me there the only thing that make sense to use is adjust/select.
I hear a lot of people stating that the ro5 is 'the only way forward' since it runs exclusivly on 32 bits processors. That just the biggest archilles heel of RO5. Yes it goes were no one has gone before in Risc Os country but if you look simply to the number of real 32 bits sw then i see that since the introduction not one application came on the market which is real 32 bit ( and not recompiled from 26 bit). Therefore , from the software pov, there is imo no sense in using RO5. We are talking here about the same software that is already available on 26 bits...
Ro4 ( + select) does the job perfectly . All sw is running without any problem at all. So , again, i do not see the point of using RO5. And therefore i do not see the need of buying/using an iyonix
Although i have to admit it is an beautiful machine
