Yep. RX8 is my DD. I put very sticky tires on it and turn the pilot nanny off. With fresh ignition bits (just replaced coils, plugs, and cables) the rotary zings to 8500 all day long. HP is fine - 230ish. Curb weight is just over 3000 lbs. Torque is just silly - I always feel like I am pulling on a really long rubber band when I come off the line. Its a long pull to get her going with the 150-odd pounds of torque, but once you are at 40 mph or so, and keeping the revs over 4500 the car screams. And it is perfectly balanced. I am convinced that it is better than the 968 stock set up in the twisties (and remember that I have a non-braced cab with a 100 year old suspension - you coupe guys with konis would disagree). It does have a wee bit of roll so a bigger bar in the back is in order.
Also a more sophistocated ride in pretty much every respect.
But, the 968 is a lot more fun. You sit lower, the engine is stronger and the car is built as a sports car. The RX8 is more of a 'sporty' car. And there ain't much you can do to address the torque problem.
As to the stying, my favorite line is from, naturally, Clarkson - "... and look at these lights, they're busier than a Bishop's hat"

If you watch it you'll see that Jeremy forgot about the styling after he drove it for a while.
I bought mine because on the test drive I got the tail loose on a hard right hander at low speed and then found myself going 80 up a fairly steep grade in 3rd gear, grinning like a silly cat - sort of like the car. And it cost about the same as my SO's van - case closed.
And as a comparo to the S2000 I would agree that it is similar. The Honda is a bit more frenetic though. I drove the bejeebers out of an example with 6800 miles on it recently (almost bought it) and I was routinely shifting at 7500. The clutch and shifter mechanism in the S2000 in my opinion is flawless - almost telepathic. It felt like a very grown up go-kart, not such a bad thing really.
