TBH, MBA trackpad failures are often caused by liquid damage, bright spots on the display are caused by pressure on the computer when it's closed, and the wifi again is an uncommon failure that can also be caused by liquid (the wifi/bluetooth chip is near the fan exhaust on the back of the top case, which can serve as an entrance for liquid). I'm not saying that all the issues you had were caused by user damage, but they may have been, and they aren't part of any larger trend with known failures.
I love how you assume by default it's the fault of my wife who you don't even know and not Apple quality control.
I feel the urge to defend my wife because you attacked her, although I don't know you and I should not care the least about personal attacks from people on the internet.
But we can't leave the internet to haters.
My wife is the most careful person I know. Her electronic devices always go into protection bags, are handled with the most care and look new after 10 years of usage.
