PS3 Or Korg Kaoss Pad 3

This is quite a weird question, but I got enough monies on the side for one of these lovely objects. I've been considering getting a PS3 for a while, only having a 360 there are some good exclusives I've missed out on. But does that really justify the £210 ($400) I would pay for it. I mean once I get through MGS4, Killzone 2, Resistance, God of War and Uncharted It will just collect dust. The other reason is that I haven't got a PS2 to play Persona on, and that has been a real bummer. 
 
On the other hand we have a sampler that looks like a hell of a lot of fun, but at the same time, abit novel. I don't use hardwear at all currently in my production, but it also looks as if it would be a killer MIDI controller (that I would have to get around to buying the extra wires, which I probably never will). 
Although it's probably something I should miss untill I am earning somemore monies, since its going on ebay for £225 ($420). 
   

 
That's a tough decision.
 
I see The Kaoss pad as more of a live performance tool than a production tool. Plus I think it's novelty will indeed wear off if you're not already a fanatic about "performing" your stuff in live with hardware - you'll find it easier and faster to just enter stuff into your software manually per usual.
 
As for the PS3 - if that's all you're gonna play on it and the BluRay stuff doesn't interest you...perhaps that would be money best spent elsewhere. Can you get a used PS3 for less? Can you rent a PS3? I remember being able to rent SNES and Genesis systems from the video store, but that was a long while ago, haha. Oh and what about borrowing a PS3? Let someone use your 360 for a week while you catch up on PS3 games. Just some ideas - probably ones you've already thought of, but whatever. :)

I would opt for the Kaoss pad myself, my Technics would love one of those.
