I've been a satellite internet user for ~10 years, I have used both wildblue and hughesnet. The big problem for regular internet use is not latency, my current hughesnet connection:

While this makes online gaming pretty much impossible, you can reasonably browse the web send emails, etc....though.
The REALLY BIG PROBLEM is bandwidth. I am on the most expensive package hughesnet provides...and that is 450MB a day. Which again is fine for checking email and 'normal' web browsing (according to hughesnet) but any kind of downloading, like for instance my new smartTV with built in YouTube and Netflix, yeah, useless. I switched from Wildblue to hughesnet a few years ago because wildblue uses a 30 day bandwidth total like most cell services, so if you use all 15GB of bandwidth in the first week, you have to wait until the end of the billing cycle to get more bandwidth. Hughesnet is a 24 hour cycle, so after 24hrs you get your 450 mb and are back to normal speed.
The other nice thing about hughesnet is they let you keep your previous days unused bandwidth, so if I do not use the internet for a day, the next day I will have 900mb of bandwidth to use, if I have 100mb left at the end of the day, I get 550mb the next day, etc...of course the "pool" maxes at 2 days worth of bandwidth. Both services also have a 2am to 7am unlimited bandwidth, the problem is it feels like the connection drops to a crawl during this time, and the normal 300 kb/s I would get during the day is more like 20 or 30kb/s. But at least I have my linux servers and windows updates scheduled to run during this time.
By the way, I live in NY, and there is not even cell service at my house. Currently it looks as if I will have satellite internet for the foreseeable future.
