Perhaps. The physics and economics of these systems, and the regulatory barriers to keeping them current means they will never work as well as what you have at home though.
Maybe, but as someone who use them regularly we've moved far beyond "hopefully check my emails sometime in the next five minutes". It's still not good enough for something like youtube, or even javascript application with a need for low latency, but it's definitely good and reliable enough to "use the internet".
I've used it on both Qatar Airways and Emirates, and would recommand it if you like to work during flight and your work needs the internet (eg emails, your task trackers to follow/answer your team, code reviews, ...), it's also been cheap enough that it fitted into my needs (paying it and getting myself up to date was worth more to me than not paying and then having to catch up after landing).
Ahh, got it. I was including "regular web surfing" along with "check your email". Just saying that higher bandwidth things like videos, spotify, etc, weren't feasible.
