Yes we still need them (many short haul ac are not ACARS equipped)
I use them almost daily especially when returning from the continent for a good heads up on the wx up north - the Volmet North can be picked up south of Paris which gives us a good idea of any likely problems at destination and alternates with an hour + to go
I would also use the Main and the South to pick up en route alternates along the route well in advance of reaching them, this helps with any diversion decisions should they become neccesary.
Ops rooms - or crew rooms in our case is all done through the internet for weather, notams, flight plans etc.
