In OP's defense, Dell is really overpriced for what they offer. From an international company you may expect their hardware to last longer then only as the warranty (that comes with the purchase) states. Hell, I had this Medion PC that I bought at the Aldi (German supermarket discounter) which lasted much longer en performed much better the my buddy's 'state of the art' Dell.
If in doubt, go ahead and go buy Dell.
