72 MB, which isn't the real world speed, as stated, isn't a lot. Thats only 9 actual megabytes a second. Now download any sizable source code project, or, upload many small changes. Or, even just a movie from itunes or something.

Good routers can go over 100Mbps, easily, and I would never think that 'less' speed is 'okay' in a world where increased speeds are just a requirement of technology over time, and usage, of said technology.
