Unless you're flying a flight of over 3 hours really the current seats are perfectly good. Where the refurbishment really comes into its own is in business class, where the seats are significantly more comfortable (thanks largely to the leg rests and footrests).
On the other hand, the lack of dividers in the refurbished planes makes the business class experience more unpleasant due to the people from economy class lining up to use the front toilet.
But especially if you're flying economy on a short flight (where reclining is unnecessary), it's in my view a little melodramatic to describe the old seats as a waste of money.
