2. macbook pro’s wifi card stopped. - I've had WiFi cards that never shipped drivers for the latest Windows OS, after just a year.
3. key failure - Valid, and pretty inexcusable by Apple
4. bluetooth never worked with speakers. - Bluetooth (below v4) never worked correctly between different brands, always had issues no matter what combo I used.
5. audio software breaking... well Windows are insanely great on backwards compability for apps, I'll give you that.
My point is that there will be issues wherever you go. I have a Macbook that is working after 10 years. I had a Toshiba that broke after just one year (soundcard). My family members have had two Dells that broke before reaching 2 years.
The only ones that have data points on this I assume are insurance companies.
