<p>First, the battery doesn’t last 10 hours; that’s just the advertised time. It’s closer to 7 hours and 30 minutes:</p>

<p>And closer to 5 hours if you’re using the i7 version:</p>

<p>Finally, as for a PC laptop with similar specs:
The HP dm4 series has similar specs to the i7 MBP with a battery life of 5 hours, just like the MBP, using the standard 6-cell battery for $729. The 9-cell battery lasts for 8 hours, and still costs only $759, still under budget. And this is without a “back to school” sale, mind you.</p>

<p>As for the Core 2 Duo MacBooks, a laptop that has similar specs for cheaper is the Asus U81a:

<p>I used this laptop myself personally before selling it for the UL30a, so I know what it’s capable of. It has a 7 hour battery life just like the Core 2 Duo MBs, yet is available for $589.99, much less than the MBs.</p>
<p>I win.</p>
<p>Finally, you don’t compare GHz. It’s just wrong. I can show you many Pentium 4s that have clock speeds close to 4.0 GHz, but they do not compare to a 2.5 GHz i7. Don’t fall for the MHz myth. You compare using benchmarks, especially when comparing two different architectures.</p>
