Bests & Worsts Reviews from Amazon

I've only had macbook laptops going back 10years, got all my family and most friends on iphones and other Apple products due to "higher" quality I've experienced over that time right up until my incredible durable last generation macbook air. Then I bought this thing in Dec 2018 (macbook air retina 2018). I had been so spoiled by years of amazing Apple quality I guess my expectations were too high for this latest macbook air. Just some issues I've had: 1. creaky body that emits a strange cracking sound like the screws in the chassis are loose yet I've confirmed they arent 2. overheats regularly to that totally uncomfortable burning hot level (never an issue in prior less powerful macbooks) 3. my "A" key is disappearing!! First time I have ever experienced any such quality issue with an Apple product! And when I took it to the Apple Store after properly making an appointment online, describing the issue and waiting patiently for my tech, I was informed "we have no 'a' keys in stock but will contact you in the next few days". Its been a few weeks, I've never heard back. This is NOT the Apple I once knew and loved for their exceptional customer support of their products. 4. And finally, my macbook air will get stuck when being "woken" from sleep mode in some weird login loop where it keeps going to the "enter your password" screen repeatedly yet I never can and have to do a hard reset by holding the power button down for a while. 5. Lastly, the whole point of this little, light laptop is its travel-worthiness, ie battery life and lightweight. Whats with the massive charger brick that feels like it weighs like half the entire laptop by itself? All in all, what the heck is going on here Apple?!?!!?! My family is probably 10+ devices deep at this moment and for over a decade and we've never had quality issues like this before! If the Apple Store fails to contact me as they promised for yet another week, I will be putting the new macbook air on OfferUp and moving over to the slick new Surface Laptop 2, Lenovo X1 Carbon, or Dell Oled XPS13.
