I got the upgrade yesterday and just did a quick tryout. First thing I noticed is it has a much nicer looking everything, grey like Lightroom and the default settings seemed to me minimal, in the past I turned them off immediately but this looked pretty good, a nice improvement over the original image without looking like I'd wacked it with cold cream and a distortion lens. Then I clicked on the healing brush and adjusted it's size and found it has not only the brush but a healing spot, much like LR and it worked very nicely. I adjusted some shine and moved the new image back to lightroom and put it alongside the original and noticed how fast it had worked.
The series of images that this one was a part of, were ones covering an event and I hadn't been inclined to do more than minimal post production but from what I've just seen in PP 10, next time I'll give it a go.
I only knew about the upgrade because they sent me an email and I clicked on the link, as a special it was only $29 which didn't seem like much, regularly the upgrade will be I think $39.
