The "wall" between gates is almost entirely window in the new terminal. So you can get a good view of the tarmac from the waiting area. However, the jetbridges are still regular walled ones.

I didn't notice any laptop stations, but I think they're there.

Easy chairs? They seem like standard airport chairs to me.

Haven't been to the new Le Boulanger. With the exception of one bar and a newsstand, everything else was still under construction.

There are still WN flights out of the old gates.

(My last flight out of SJC was almost a month ago. I'd be surprised if any new gates have opened, but its possible new stores may have.)
