Macbook pro died after four years

I bought macbook pro four years ago. It cost me 1000$ and I pumped into it other 300$. About two weeks ago my macbook suddenly shut off while i was using it and wont turn back on. I tried everything. Today I went to Apple and they told me that my motherboard have died and repair will cost me 600$. When i asked how can such an expensive good think just died after four years and they told me that "it happens". So now i have every data in my dead macbook and i can throw it away.

My note to Apple: What a quality...go to **** !!!
