I’m in the middle of this. There’s good and bad points.
The good? I can watch my fave movies on my laptop and NOt rely on some crappy movie from the airlines, and surf the web.
The bad? 1) “snooping” people sitting beside you 2) batteries 3) more inconsiderate tech-jerks: cell phone users who WILL talk loud etc. 4) the filter issue: I dont want my connection being censored/filtered/watched on just in case “I look at porn sites”.
I used to welcome a conversation if the flight is long, but nowadays, I notice passengers keep mostly to themselves.
