I've done a few Tooway installs for folk in the sticks who can't get DSL or even 3G. Trouble is the satellite is geostat at 22,000 miles away so the lag (ping usually around 800ms) makes it feel really slow even though download speeds are up to 50Mbps.
Like everything else, I'm sure the prices will drop as more and more customers sign up - let's hope the speeds don't drop accordingly.
