It's coming at bmi, we already have a test aircraft with the gear installed. A large server sits in one of the overhead lockers down the back, all the "no smoking" signs have been replaced with "no mobile" signs (I kid you not) and the smoke sign switch in the flightdeck has been changed. No smoke signs now appear on the little lights in the PSU above each seat that used to light up when the doors are opened, there is also a master switch on the overhead panel to turn the server on and off.
I guess they think it will make some money but I reckon it will hack a lot of people off, ghastly thought if you ask me.
