This is why you don't need fast internet:

1mbps plan gives ~100kB/s real dl speed

100kB/s x 60s/min = 6MB/min

= 360MB/hr

= 8640MB/day ~ 8GB per day

How often do you dl 8GB worth of stuff?

And if your dl speed is slow (~10-20kB/s) due to various reasons, all the less reason you should subscribe a faster plan.

Unless you enjoy paying more than $60 per month for the bandwidth and free gift that you don't need.
