I've done quite a bit of research on this, because I'm stuck on 26.4k dialup, and Verizon hates me and won't remove the load coils from my lines.
Satellite internet truely isn't worth it, unless you meet 2 conditions: 1) somebody else is paying for it (It's big bank, in the hundreds to install, like $300+, and upwards of $90 a month... I was quoted $500 install, and $120/mo for my location) B) You're a LIGHT user. Strictly browsing and email only. Not even streaming audio or music or game demo downloads. The "Fair Access Policy"(a load of crap) limits you to downloading a set amount of MB in a set amount of time, and if you go over that limit, you're throttled down to 56k line speeds. It takes many many hours to get un-throttled, because your cap has to fill back up completely. Think of it like an interweb capcitor. Each provider has their own caps, and nobody spells it out. Phone reps don't mention it, and are reluctant to give any info on it, even if you ask. It's a total crock. Also, as mentioned above, the latency is horrible, worse then dialup.
It's just overall not worth it with the price they charge for the services they offer. Probably cheaper to move into a cable/dsl area. heh.
Hope this helps.
