Look at it this way:
The nueron OS will never be updated (EVER) again.
The virus TI will probably be updated maybe 2-3 more times,Still remain buggy and then a TI mk2 will be anounced while the original TI will be taken off production
The nueron (hardware version) is rather stable as far as i know\read and its the ultimate tool for soundscape\ambient music.
I wouldnt trade the TI for it tho...
