   <introduction><p>In case you missed it, we tore apart the new <a href="/Teardown/MacBook+Pro+15-Inch+Retina+Display+Mid+2012+Teardown/9462/1">MacBook Pro 15&quot; Retina Display Mid 2012</a> last week. Inside, we found a whole mess of pretty, yet difficult to access components. In fact, the MacBook Pro with Retina display earned our lowest repairability score ever, with 1 out of 10 points.</p>

<p>What we didn't look at earlier, however, is the MacBook Pro's namesake: the Retina display. Apple claims that the Retina display in the MacBook Pro is the most stunning display to ever grace the lid of a notebook computer. &quot;<em>But at what cost?</em>&quot; we find ourselves asking. Being the repair-minded folks that we are, we feel that the only fair way to answer that question is to give this new display &quot;the iFixit treatment&quot;: open it up and look! We may not be opthalmologists, but we are excited to be doing surgery on a Retina display. Join us as we investigate the intricacies of Apple's most stunning display.</p>

<p>Do you wake up in the middle of the night, tossing and turning in anticipation for iFixit's next teardown? <a href="http://www.twitter.com/ifixit" rel="nofollow">Follow us</a> on Twitter and get some rest. We'll keep you up to date with all the hottest gadget teardowns!</p></introduction>
