Dell’s designers have kept the looks of the new Inspiron 5559 as simple as possible. The plastic lid has an interesting jagged texture which feels nice to touch, seems durable, and most importantly – doesn’t attract fingerprints and smudges. Okay, maybe the durability should be of greater importance but we can rest assured, considering that the American company never makes compromises in that regard. You might be able to guess that when you notice the 36 month warranty ( check terms and conditions for your country) . If that’s not enough to convince you, take a look at the tests that Dell conducts on every Inspiron prototype model: Every Inspiron has to survive short-term heat conditions of up to 65°C/149°F, opening and closing the lid 20, 000 times, 10 million keystrokes and twisting the laptop’s base and lid more than 25, 000 times.v ery best laptop.
