The jury's still out for me at the moment. My first impressions are that the new look is pretty awful but maybe some improvements will get made.

One URGENT improvement is needed to creating links within a post. You used to copy & paste the URL - then after hitting Okay you could type in some human readabe text. Now you need to backspace, delete the text it inserted automatically and replace it with your new text which is a huge step backwards. Even the previous method was a huge step backwards from the one before that - where you typed both entries into a dialog box.

Don't like the fact either that if I move the carat while typing, it seems to disappear and I can't tell where I'm going to insert stuff.
