<p>Asus tried a few years ago. The result? 50% thicker than the MacBook Pro. Eight pounds. One hour of battery life while gaming, “more than double that” (2 hours 10 minutes, probably) while doing productivity work. A huge fan/hearsink unit protruding from the rear.</p>

<p>All this so you can use a desktop CPU and have the option to upgrade the video card (but not standard desktop video cards).</p>
<p>On a MacBook Pro today, removing one panel exposes the RAM and hard drive, both of which are officially user upgradable. I’d rather have a system that sips power and is relatively thin and light, but doesn’t have a user upgradable CPU or hard drive.</p>
<p>Honestly, I can’t conceptualize a way to build a completely upgradable laptop with standard components that is reasonably sized. Can you think of a way?</p>
<p>If someone really cares about upgradability, he’s going to be building a custom desktop, with an Antec case and an Asus or Gigabyte motherboard. Most people want to buy a machine that does what they want it to. </p>
<p>Sure, there’s a market for custom tuning cars, but most people–rich or poor–just want to buy a stock Mercedes or Toyota.</p>
