Please forgive me if these were already mentioned (I haven’t had time to read through the thread yet).

1. I like the fact that all of the window seats have access to an actual window. One of my biggest complaint about the current Polaris setup is that the even numbered window seats often don’t have a good window.
2. If two people are on the same itinerary, I’m hoping one can book a Polaris Suite and the other can just book a regular Polaris seat. Wifey and I both like window seats, but we’d like to hang out together mid-flight for a few hours as well.
