I got my Cloud+ today and I'm breaking her in. I took some side by side pictures with my old clicker for comparison.
In this picture below, you can see the difference in the shape of the bamboo's tail. The + on the left is the new straight design (I believe this plays a role in making the bamboo replaceable now) while the clicker is flared. You will also notice how close to the surface the + bamboo sits. It was extremely close to the surface, but I had to push it up about 1/8" anyway because the top joint was sitting too low to mate with the HT.
In the photo below you can see the new temperature knob. I have to say that I prefer the older knob much more as it is difficult to see the line from certain angles on the new knob. Light reflects in strange ways around the knob so it's hard to see the line unless you're looking at it just right. Of course my eyesight is total shit, so this may not be a problem for younger eyes. You will also notice the +'s joint is setting a little low. I took this pic before I pushed it up a bit.
Here's a shot for the ass men like me.
The warmup time is very similar, if not exactly the same IMO. The Plus turned green in under a minute (54 seconds to be exact), however it was still dead cold. I took a rip just to make certain, and I got no vapor at all. The old clicker turned green after 14 minutes, and at that point they were both about ready to go.
I've been hitting both with equal sized ELB loads of Yoda Kush, and they both hit like Ike Turner. No complaints at all. I don't think a blindfolded person could tell any difference in hit quality. Fantastic fucking device(s) is all I can say.
Back for more testing....
Edit: After a full hour of run time, the Plus is a full 10°F cooler on the outside.
