My reasoning is this:
All laptops WILL eventually break on you and then cost a ridiculous amount of money to repair. So, two strategies:
1) Go for something that has a 3-year warranty (Asus, etc.)
2) Buy the cheapest laptop there is (i.e. Acer) and deal with it when it breaks
Also, desktop PCs are not very future-proof, but laptops are even less future-proof. It doesn't make much sense to buy a monster, thinking it will last you a long time. It won't.
