Work(10gbit fiber ~ from my VDI... it was maxing out the CPU. I'll retest on my MacBook tomorrow in the office... usually it maxes out my gigabit NIC):
I live in the boonies, it's a wireless radio connection, no data cap. AT&T Cellular is wicked fast here as an alternative, but the caps are so low it's essentially useless for anything but web browsing.
At the beginning of the year they doubled my download, but my upload actually went down 2 Mb/s. I guess I'm technically paying for the 25/5 package, but before I usually averaged 30/8. All I know is I wish I had Forethought in my neighborhood, since they offer gig fiber for $70/mo, like Google fiber.
