My post from ducatispot.com:
...I had a 08 848 and thought I loved it. I purchased a Honda 1000rr to commute to work on, didn't want to rack up freeway miles on the 848. What was weird to me was that when riding the duc, my body felt rigid and jagged as opposed to the 1000rr where it felt as if my body just melted into the bike. For the longest time, I couldn't figure out why until I noticed that the shape of the tank where your stomach/chest rests is completely different. The 848 is a sharper angle up (like 80deg) and then slopes down towards the front, while on the 1000rr, the angle is larger, like a 60deg angle. I found that it was the shape of the tank that threw me off. Long story, I ended up selling the 848 and keeping the 1000rr. Fast forward to now, have a panigale 1199s and absolutely love it. You'll notice that the tank angle is a lot like on the 1000rr or even the S1000rr, more of a gentle slope and not a sharp angle. Body just melts and totally fits her. Looking back, I would not get the 848 again but I'd purchase a pani all over again.
Regarding the heat. That was also an issue with the 848 or even the 1098/1198 for that matter. The route that the exhaust takes, plays havoc on your inner thighs and then having the exhaust under your a$$ doesn't help much either. The pani has heat also, a little different from the 848 and it was a concern that I had myself prior to purchasing but it's not bad at all unless you're stopped in traffic. When you get going it's fine and I live where it get's to 105 at times.
