I just hate it when everyone is being so unfair to Nadal just because he plays an "unorthodox" game. Out of all the players who uses full poly, he is the most successful, that means he must be doing something right. Why can't people leave it at that?
There's no such thing as being "more reliant" on technology. Everyone is helped by modern racquets. Federer doesn't have the most classic technique on his groundstrokes either.
