I happened to wander around John Lewis's electronics sections yesterday (for the uninitiated it's a chain of upmarket department stores in the UK) and I came across an "ultra-fast" HDMI cable, 1 metre long that retailed for 59.99 pounds (or about 94 dollars). Only recently I bought a 2 metre-long HDMI cable for 2.99 (or about 4.70 dollars) that I have been perfectly happy with.
Is there any practical difference? I mean the price difference is just staggering, what more could I possibly get by shelling out for such an expensive HDMI cable apart from possibly better coating and that swivel adapter? Are these cables really faster and in what respect?
