I used the Boeing service on an SAS flight to Copenhagen and loved it. The problem wasn't with the Wifi. But there was a major problem elsewhere that'll keep people from using it: power.

My batteries in my laptop (and in most laptops I see on planes) last about two hours. Yeah, some models last four to eight, if you have additional "big" batteries. But most last about two hours the way you buy them out of the store.

So, how do you get power on the SAS flight? You have to buy a $250 upgrade each way. Prohibitive for most people. I actually tried to upgrade cause I wanted to do some work. Turned out those seats were sold out in both directions.

Long and short of it is that we aren't going to see Wifi in most planes anytime soon.
