My system works very well, download speeds similar to cable. I don’t upload big files. Yes, there is a 2-3 second lag for the signal to travel to and from the satellite. And upload is not much faster then dial up. You get used to it. My experience with DSL was not good. To each their own. The technology is different and relatively new. For some, satellite is a viable option. There is even airband now...
Other than that, it's great. It's better than dialup, but way way worse than DSL, which is second. Cable is best, of course, at least until we get FiOS.
