<p>The U43JC has an advertised 10 hours battery life. In my experience, real-world battery lives are usually 2-3 hours less than advertised, so I’d estimate the real battery life to be 7-8 hours.</p>

<p>Piece of cake for both. Asking about HD movie playback for the GPUs is like asking how the i5 handles Microsoft Paint. Both are definitely more than enough here.</p>
<p>
</p>
<p>Unless you get Photoshop CS5, this is more CPU-based than GPU-based. As with the first, however, this is still easy for both GPUs to do.</p>
<p>

<p>Purely a CPU application, does not involve the graphics cards.</p>

<p>WoW is in reality not an intensive game at all. I’d daresay both of these GPUs can play the game at medium-high settings (depending on resolution). The M11x’s graphics chip only pulls ahead in intensive games like Battlefield: Bad Company 2 or Metro 2033.</p>
<p>Going to grab some food now, I’ll post later after I search for benchmarks.</p>
