When I first heard about it, I was very excited, and wondered how it would fit in with an arranger. However, when I saw all the demos, I realized that even though it's a very nice keyboard, it's not for me. So, to answer your question, no, I did not order one.
I was disappointed that it uses old Roland sounds like the ones in the XV5080 (and others), and not the latest ones like from the Integra-7 and newly sampled ones.
For me, I think the PSR-SX900 coupled with the MODX will be the best fit. Unless something else comes out soon.
