I've been using it all this last week and think it's really amazing. For those of you who say it's too much, imagine not buying a car because the speedometer says it will go 120 miles an hour and you don't want to go 120 miles an hour. Well PP 10 offers the opportunties to go way beyond your needs and turn off the default, there's a button that's for on or off, you can set this up to do nothing at all like your Lightroom or Photoshop where you start or it will give you a default. It's like choosing to switch off AUTO on your camera, it's a choice. Just consider it like RAW in your regular processing, you can start at the beginning and just do a tiny, tiny, tiny bit of just a huge number of things separately or in bunches, it's all intuitive and all you have to do is select your choice and then use the sliders or the brush. And it's incredibly fast to use, I'd say that this week I cut my processing time into less than half from what I was doing before which was a cross between PP9 and LR3 with occasional trips over to what little I can do over in Photoshop.
I don't know why I'm bothering here though, it'll just make you people better faster huh, well duh!
