A couple of years back I was at a conference in Rome. Literally in the heart of the city (the windows overlooked the Forum) and that meant that they had only satellite access because nobody had run cables through the historic buildings. I've never been more glad to have spent time optimizing our site for 2.5-3G performance than when we were demoing it during presentations and it seemed slow but almost everything else was unusable.
And that's still great internet compared to some places. I have a house out in the middle of nowhere that is only served by a single satellite internet provider (surrounded by trees that block the view to other providers' sats). I get 20Mbs at ~500-1000ms latency for a few days before I hit the 20Gb cap, then I get 0.5-1Mbs for the rest of the month. Hacker News is one of the few sites on the web that I can browse relatively painlessly when I'm up here.
