I&#x27;m not sure why people are having so much trouble with this question, which can easily be restated as &quot;why can&#x27;t someone build a laptop that has <i>at least as good a display as what Apple calls a &#x27;retina&#x27; display</i> while having the same battery life as an rMBP?&quot;<p>An easy answer to that question would be to submit for consideration some non-Apple laptop that accomplishes that. I&#x27;m sure it must exist, and that would be a good thing to know about.<p>That there is some random Dell laptop with <i>better</i> resolution than a retina display and <i>worse</i> battery life is simply not responsive to the question.
