Dan, you don't have to convince of the benefits about MixCraft.

No keyboard can match the power of a good DAW..
The G70 touch screen and sequencer is much faster to come up with a product.. It depends to what level of production you need..
Making backing tracks for stage.. give me the G70

For a masterpiece high end product.. give me MixCraft
The trade off is time and the work flow when you have an idea.. G70 wins here..
There are few if any other keyboards that will measure up to the G70... For those folks ..yes DAW is the answer.
