Whats the advantage between 20mb and 50mb broadband speed..?

the difference is about 1.5 times faster. 20 mbs is pretty insanely fast if you are truly receiving a 20 mps download. At that speed I would think a 50 mps download would be like splitting hairs. Literally seconds faster. Depending on the size of the download and how much yhou download and how much more expensive the 50 is, I'd probably just stick w/20mps
