I guess for single travellers its an improvement. Revolution: no, evolution: yes.
For couples its a step back. Even though the divider between the 'old' E and F seats is rather substantial in the 'down' position, one can still have contact. On the (admittedly few) occasions I have flown F, there has always been (another) couple. So based on a very small and certainly not representative sample, the F cabin used to appeal to couples, the new one might not.
Maybe one can set the 'virtual window' to look into the other middle suite and vv.... (here I want to insert a smiley but the new forum format wants me to 'Go Advanced' to do that, wat a bother..
Looking at the lack of 'game changer' elements and the small number of planes that appear to be going to be equipped with the new suite, it seems mainly an expensive marketing hype to me. (another emoticon please)
