I've had one for about a month. It really is awesome. The quality of the sounds is generally better than aything else I have heard. The playability is also superb. It has 12 insert effects which which is way better than my Fantom X, which only had 3 and which I found quite frustrating. Don't get me wrong, the Fantom is a great keyboard its just the Oasys is spectacular, as it should be given the price difference. When I first heard about the O's feature set, I thought this is for me, then I heard the price and thought NFW. But I got to hear and play it and see it demo'd at the nearby Guitar Center, and I was hooked. Programming sounds on it is a dream with the large touch screen and the excellent GUI. The drums are so tweakable, you can individually set the EQ and level on each item in the kit. The only thing that really needs a lot of improvemement is the sequencer. It is usuable but is a lot clunkier than the Fantom. Rumor has it that Korg is working on enhancing it.
It has so many cool features like the wave sequencer, vector synthesis and Karma. The Karma unit can do so many things; it can produce extremely realistic guitar strums, great drums fills, and great backgrounds comps and lots of stuff I have not even explored yet.
I highly recommend hearing it for yourself if you get the chance.

I love to play piano on that one. Sounds just like a real acoustic grand. None others could beat.
