Sorry. I don't know how I made that mistake... I meant 128 Kilobits per second (16 KiloBytes per second). The best you can get is 1 Megabits per second (128 KiloBytes per second).

I have a 256 Kbps connection. It's really, really slow. It took me 2 days to download OS X Lion from Mac App Store (about 3.5 GB).
