We have satellite (HughesNet) as that is our only option here besides dial-up (no cell service for 20-30 minutes around). I have to have it for work as I am field-based and work from home when I'm not out visiting customers.
The other satellite provider (WildBlue) was not an option as their installer refused to install a dish here (said there were too many trees).
Our plan costs $65/month.
We have a bandwidth cap of 425 MB data download per 24 hours (there is a 3-hour grace period in the middle of the night). This is called the FAP (Fair Access Policy). If you exceed that then you are punished with ~1 kbps for the next 24 hours. You learn quickly not to exceed it. We have a little utility that monitors our usage (but it doesn't work very well). You can also use download schedulers so you can have downloads happen during the grace period.
Basically the cap means that we don't watch any videos or play games. Pictures are ok but we try to avoid picture-heavy sites (especially from people who forget to reduce the resolution before they post). VOIP would suck up too much bandwidth. Web-surfing all day long without videos or gaming is pretty much fine. I set Outlook to only download headers automatically so I can choose which emails to download (some colleagues seem to think it's no big deal to routinely send out 20-30 MB attachments).
I can do some webexes for work, an hour a day is fine but I wouldn't do it for much longer. The performance is not great because of the latency but it is tolerable. The security protocols in VPN do not play well with the satellite technology and it is basically unusable. Dial-up is better than satellite for VPN. Uploads are also very slow.
Anytime I need to do serious uploading or downloading, webexes where performance is critical, or use the VPN, I need to ride/drive to somewhere I can use my aircard or Peet's free wireless (30-minutes one-way is the closest).
The performance is better during the day than in the evenings. Bad weather makes it very flaky. Multiple people using it definitely slows it down.

If cable or DSL suddenly came available, we'd probably fork over the $400 early termination fee to quit the satellite (it's that frustrating). However, I will happily keep it so as not to have to depend on dial-up.
