&gt;<i>I bought a Macbook Pro and it was horrible. I got the old Macbook back and the Pro which should be faster was slower. Brought both to Apple (in Amsterdam) and they said it had something to do with my software. Yeah. VIM. It&#x27;s super heavy. Very nasty experience. Battery life on the Pro was not there either but they couldn&#x27;t find anything so I had to suck it up.</i><p>Are you implying there was some hardware reason your Macbook Pro was slower than an older Macbook?<p>And contrary to all CPU&#x2F;HD&#x2F;Memory specs and benchmarks and reviews for the respective models?<p>I&#x27;d be surprise if it was not software related.<p>And while you might &quot;only&quot; use Vim, that doesn&#x27;t mean much. I&#x27;m pretty sure you also browse, check email and do other things, so you do use many apps, Vim is just what you use most frequently.<p>In any case, all it takes is a single rogue app to make a machine crawl -- some haxie you installed that provides some third party functionality but don&#x27;t consider an app you use because you don&#x27;t interact with it, or even Spotlight with a corrupted index.<p>&gt;<i>A friend told me the Macbook pro is excellent. So I gave the Air away to a friend and bought a kitted out Pro. The misery. No battery life and it was slow with max mem and cpu. Slower than the Air on everything. Again; Apple says it isn&#x27;t. I won&#x27;t mention Vim again.</i><p>It&#x27;s not just Apple saying those machines are faster.<p>I can&#x27;t understand how a developer (since you use Vim) can make such statements. It&#x27;s not very difficult to compare the specs of the baseline configurations of the two models.<p>I&#x27;ve done heavy graphics, 3D, 4K video editing and DAW work on Macbook Pros and Airs -- while recent Airs are decent, there&#x27;s simply no comparison. And it&#x27;s trivial to show it in all kinds of benchmarks and tests.
