Took my 2010 F8 LE out for the first ride today and I was seriously impressed with the sled. It had everything I loved about my 07 (comfort, fuel economy, rear suspension quality) and added a ton to it. As mentioned earlier, it does feel considerably lighter than the 07. Additionally, the motor is just plain and simply bad-***. The power comes on early and pulls hard throughout. And the greatest thing, they improved the handling a ton over my 07, yet the thing still doesn't dart and the steering never felt heavy. The thing carves now.
The only thing I wished they did was skinny the seat down a bit. It might not bother some people, but it still feels a bit wide for me.
If anyone was on the edge of buying one, I would whole heartedly recommend going for it. You won't regret it.
