I may have missed it, but may I assume a device license is transferable? I mean to transfer it when I ditch my Mac for a new one, so I'm talking about my devices only. I'm just asking to be clear, especially given use of the word "lifetime". Thanks!
OK, in all fairness I did think all we were talking about was the trigger, not the underlying vulnerable system (which I already had understood to be less than solid over the years.)
My first thought was that airplanes need noise canceling for the engine sounds. There's a real difference in a long flight with and without noise canceling headphones. Effective (better?) noise cancelation for the whole cabin would be impactful.
I'm definitely not an expert, but I would say nothing of note has changed with our utility bill since we replaced the gas cooktop with an induction cooktop.
The marketing will tell you it's more efficient because all the energy goes into the cooking (heating the pot) instead of heating the room as with gas. But hey, that's marketing.
One other concern was control: we did find out that the power levels on our model were not linear. The first 5 were all low power for low power needs (eggs, sauces, etc) and then 6 through 9 were much larger increments for high power needs (e.g. frying).
Our experiment before committing was using a plug in cooktop. We got a good one, and even though it was "only" 1800W it made many meals. It's power settings were linear but offered us 0-100% in 1% increments (amazing control! Love that thing.)
I've seen that forever and not just on United. I have thought it's something about the underlying SABRE system that many airlines use. Maybe someone here knows more.
