I'm not familiar with Spaceway, but I have checked on Wild Blue. It is no longer offered in Michigan, and won't be until end-of-year. There transponders on the current satellite are full and the new satellite won't be operational for Michigan until last quarter 2006. I was also told that Direcway uses encrypted video signals, which slows things down, compared to Wild Blue, which does not (all digital?).
Also, browsing is mostly what I do, so I was curious which DW7000 improvement increases the browsing speeds over the DW4000?
