Great: if you have a talent for playing music by ear, you can throw this talent into the garbage can now and take software instead. Computers will destroy music completely.
Edit: Luckily these programs don't seem to work properly YET, according to the customer reviews.
Software will never compensate with natural musical ability. Besides Phillip was asking about scoring music that he can already play so your criticism about using that software doesn't even apply here.
If you have problem with people that use music scores or charts maybe you should start a new thread on that rather than hijack this one. I think you will find many musicians use scores or charts. There is no shame in doing that.
