I&#x27;m pretty pleased with the specs on this, because it&#x27;s perfect for my usecase:<p>I currently use an ipad 4, with its 10&quot; screen, as a second screen for my mpb retina 13. I like this setup because it&#x27;s thin and relatively light so slots easily into my bag along with my macbook, and doesn&#x27;t require a power socket to run, just USB. I also use the ipad for reading and a few other tasks so carrying it around has intrinsic value in addition to  being a second screen.<p>The ipad 4 does a reasonable job, but it&#x27;s a bit on the small side. This new pro form factor is, however, perfect - 12.9&quot; and higher res than my mbp retina screen means it really can be a true second screen, with roughly identical capabilities to my main screen. I&#x27;m pretty happy about this.<p>Won&#x27;t be upgrading just yet on account of the price, but when it drops enough, replacing my current ipad with this will be a no-brainer.
