OK, I'll bite. Why on earth not??

I think the new F looks like exactly what I want from an F seat. Wide bed (which reclines instead of folding down), big TV, private but not claustrophobic. I also like the colours of the F seat.
C looks okay as well. Same as the new OZ seat and similar to the LX, EY, EK seats. You get a good flat bed albeit it looks a bit narrow for my liking and every single seat has aisle access! From a business point of view this seat looks great.. Fully flat to make the customer happy yet they still manage to retain a high capacity. If TG went for something similar to SQ then we would probably see the TG fares go up massively!
Y just looks like normal modern Y seats.
What is not to like?
