Hmmm. My previous laptop lasted almost 10 years. I took it back and 
forth with me to work, where it sat playing music for me. So the USB 
connections were being plugged and unplugged at least 3x a day, 5 days a 
week. 6 days a week when I started using it to record our church 
services. The connectors and cables lasted fine the whole time.

They outlasted the motherboard power connector!
