80% of computer related work carried out in my Accountancy Practice is with a pair of Iyonix's using ultra reliable software such as OvationPro, Schema 2, NetFetch, Messenger, etc. Whilst I have Ovation for Windows, the RISCOS version is nicer to use and Schema 2 is far more user friendly than Excel despite its limitations. Netfetch and Messenger ensure that our systems are not infected with nasty Windows viruses and RiScript converts documents for export to anyone.
We have to use PC's for tax software and internet work but only when absolutely necessary.
I am quite happy to support RISCOS as long as users are supported and at the moment I think that support is there. I still receive free updates of programs purchased some time ago and have no reason to complain about anything.
I am confident that I will the Iyonix's will only retire when I do which is still some way off!
