Reason is a toy anyway, not because it lacks something, but because it's so fun to use.
The features missing in Reason 6.5 are not stopping you to archive your goal - making Pro sounding music that is.
Well, I'd understand if Reason would still lack audio in and 3rd party plugins, but that's not the case anymore.
Audio quantize isn't needed to record good sounding audio, now is it?
The features that people hope to see are nowdays "Second Hand" features. (Not important at all).
To me, Reason is the best option to make music. I've heard often enough that my music sounds Pro and I've heard lot of great music made with Reason. This is all that matters in the end - we are able to make top quality music - so why call it a toy?
