Map of (Swedish) 3G bandwidth with real-world data.

Zoom in. They have done a very nice job of decluttering as you zoom in and out.

From zooming in and out of Helsinki, it appears they are averaging the bandwidth of the aggregated samples. I think I'd prefer some sort of indication of "how bad is the bad". Once I've got a megabit I don't care, but if I have a 20% chance of an unusably slow connection, I care.

Just say that the information for other countries –outside Sweden– is pretty inaccurate (they should only show averages for more than 5 tests, and using 3G, not GPRS/EDGE, etc.)

But still interesting!
