My first impressions. What I like:
1) I like the Kudo icon being closer to the posting user, makes it more obvious. But I think it would still help for the Icon to be labeled with "Give Kudo" or something like that.
2) I like the Reply button being near the bottom of the post. This helps particularly for the longer posts so you don't have to scroll back up.
3) I like the overall look and feel in general better than it was previously.
What I don't like:
1) As someone said above the default font appears to be a bit small. Though it works for me since I tend to use pretty small fonts anyway, it could stand to be increased 1 or 2 sizes.
2) Hitting Cancel sometimes takes you back to the wrong page! In just about 20 minutes of doing a bit of testing I have found that if you reply to a post and then hit Cancel, it sometimes takes you back to the wrong page. In a couple of cases already I responded to a post, hit Cancel and it took me back to my PROFILE page instead of the thread! In another case hitting Cancel actually took me back to a different thread altogether!
3) PM Icon - as someone said above, sorry but this is bad. Many users were missing the indicator that they had a PM as it was, now unfortunately it will be FAR easier to miss than before. It is simply too small and there is NO indicator of a PM except a tiny number changes to 1 or something. I sent myself a few test PM's and this just does not work, way too easy to miss.
4) Tags - I miss having a snapshot of my tags on my main profile page. Now I have to hit My Settings > Tagging > Tags to see my list of tags. Can't we go back to having this on the main profile page? Or at the very least have a link which takes you directly to your full tag list?
5) Attachments vs Images - I and others had suggested before either having images be able to be uploaded via the Add Attachments link (and somehow added to the workflow for getting approved by a moderator) or at the least having better help available so that users know the difference between the two and which one to use. I'm not seeing much/if any change here. The natural inclination will be to hit Add Attachments even for images, intead of the green tree symbol. If you add a JPG from Add Attachments you don't know there is a problem until you hit Post and then it tells you that you have a bad extension but offers NO help on how to attach the image properly.
6) When you hit Reply and then write your reply and hit Post, it takes you back to the beginning of the page instead of to the post from which you hit Reply like it did before. A bit annoying. 
I'll add more as I have a chance to look around more.
Thanks
