If you can't get Internet any other way, satellite Internet is an option, but it should generally be your last choice when you have exhausted all other options.

Satellite Internet has several issues which make it less than ideal.  The first, and least important, is latency.  Latency is not speed, exactly, but it is related.  Latency is the amount of time it take for a request to be carried out after that request has been placed.  To put it in laymen's terms, imagine a runner on the starting line.  There are two things which will affect his final time for the run.  The obvious one is how fast he runs.  The one we don't really think about much is how long it takes him to start running after the starting pistol is fired.  That is latency.  It has nothing to do with his speed, but it does affect how fast he will get to the finish line.  Although satellite Internet speeds may be fast, the typical round-trip latency of an Internet request under perfect conditions is more than half a second.  While this doesn't seem like much, this is incurred every time you "do something" on the Internet.  Every time you go to a page, half a second.  Every time you start a download, half a second.  This can add up if you use the Interet a lot.  It can also make tasks like streaming video very difficult or even impossible.

A way bigger issue than latency is data caps.  All satellite Internet providers have data caps to my knowledge.  This one actually makes it impossible to stream video on services like Hulu.  Satellite providers have data caps so small that you simply cannot stream video using a satellite connection without burning through your monthly data allotment in days.  When you've reached your data limit they will usually slow your Internet down to a crawl, sometimes for the rest of the month.

Another issue is weather.  Satellite Internet has the same weather issues that satellite television has.  When it rains your Internet will go out.  This is because water tends to absorb high frequencies very well.  There is no way around that limitation currently.

Another issue is the price.  I haven't looked at the prices for a few years, but the last time I did satellite Internet was the most expensive, slowest and most limited Internet connection you could get.  There was no worse choice than satellite, at least at the time.

Still, if you can't get literally anything else, it is an option.  But DO NOT simply choose the service you saw in a television ad.  Look at your options first.  Satellite Internet providers may offer vastly different services at vastly different prices.
