These are all great improvements. I agree that everyone has a device now (even for children...), and the iPads in Prem Rouge are unnecessary.
I actually forgot that there used to be PDB and hot towels.
Priority access to lounge for J / SE is a big plus. I stopped trying to go to MLL's at times now because there's just no room.
I flew a 3 hour flight recently a 7M8 without wifi and had planned to do work... I hadn't flown a 7M8 in a while and forgot about the lack of wifi. I think this will be the biggest improvement.
