ur firned's advice is not 100%. although its a safer bet tat premium price will get u premium build.

Reason:

1) expensive laptop doesnt guarantee zero-faulty units.

2) My whole family (around 7 of us), using around 4-5 laptops, and all our laptop are between the price os 1.5-1.7k. All of it lasted at least 4-5 years (minimal gaming). We only change laptop when it lags significantly. [this conclude tat how u use ur laptop also plays a factor]
