With several laptops, an iPad', Apple Tv, airplay connections and a 'very' hungry hardcore gaming PC sookin' up available bandwidth I reckon I'll see quite an improvement.
But that's the thing - I really wonder if you will be able to tell any difference at all once you are upgraded. Unless it is purely a large download, you will still be stuck with the same speed that sites can actually deliver.
It potentially means that all the people on the very lowest band, suddenly find themselves able to do more and the whole network just crawls.
Guess we'll have to wait to find out.
