However your primary point might be correct - European windows are much better - how they can open sideways and from the top - I've never seen that in the states.
Also they eliminate the need to transfer clothes from the washer to the dryer, which is a major convenience.
These combination automatic washing machines are wildy popular in Asia, where seperate dryer appliances are virtually unheard of.
I'm thinking some of the push back against these machines might be from Appliance makers who would prefer customers buy 2 appliances instead of one.
These are tradeoffs, and there's nothing strange about that. Personally, I have looked at getting both, but the cost and tradeoffs (given how my kitchen is already set up and the amount of laundry we do) just didn't make sense.
And most induction tops draw so much current that you need at least 2 phases, but optimally 3 phases installed.
