Is The Yamaha CK61 Any Good?

This is the Yamaha CK61. It's a 61 note stage keyboard and has 128 notes of polyphony. In Australia its street price is just under $1400 Australian Dollars at the time of shooting this video. It doesn't sample. Nor will it play back custom samples It won't allow you to create synthesised sounds from scratch like you can on a 'proper' synth. It doesn't even let you heavily modify its existing sounds, limiting editing to a filter, an amp envelope and effects. And it's not a workstation. While a workstation will commonly allow you to split, layer or otherwise access 16 different timbres at the same time, the CKonly has access ... to just three. So can this entry-level, semi-pro keyboard possibly be any good?
