I had Verizon 50Mbps tier and had a hard time finding use for it. Giganews was about the only servers I could find that could serve me at 50Mb, otherwise I still saw a typical 20-30Mb on the high end.
I max out my 50mbs FIOS connection on a regular basis. I'm hoping they have a free speed upgrade to 60mbs or 70mbs now that Comcast is offering 50mbs service.
I pay $90 a month for my 50/20 tier which is an excellent price for that speed. But even 50mbs seems slow after awhile. I want to go faster!
