Apropos is an interesting concept - they've taken over all of the gate seating and turned it into a restaurant where you can order food & drink via IPad. The IPads can also be used to surf the web, check email, etc. All of the tables have charging stations, which is really nice.
It's not very clear that the seating is truly open - you don't "have" to order anything to sit there, use the charging stations and enjoy a more comfortable seat. That part is definitely nice.
On the minus side, the space fills quickly and adding in tables means less overall seating. If several flights are departing in quick succession from nearby gates you aren't likely to find a seat at all.
Again, it's an interesting concept. I like it when I'm able to grab a seat and get some work done and I hate it when it's overcrowded and there isn't enough space for all of those people and bags.
