No A/C power is an interesting choice, but I suppose I don't mind as long as those USB-C ports are at least 60W.
Glad they're going to 40" seat pitch, which is more than most western carriers. Having flowing CX PE on the A350, IMO 2-4-2 is still a bit on the narrow side on the A350. I believe this makes the seats themselves narrower than 2-3-2 on the 787.
I hope the "wellbeing zone" has plenty of bathrooms, since bathroom access is one of the most annoying parts of the current 787 PE.
A groove on the tablet for phones/tablets is good, but I much prefer a mount on the back of the seat for personal devices, like e.g. Cathay economy. The current PE seat's "tablet ledge" isn't great either.
