Don't know how many of you saw the announcement this morning, but B&N is converting PubIt! into NOOK Press. I signed up and played with the new service this morning. I don't know much about what PubIt! was like before, but I really like the feel of NOOK Press. It's very sleek, easy and intuitive to use, and I keep finding fancy features around every corner.
It looks like they've also made some changes to royalties, etc.
