<p>btw, what do u need the lappy for?</p>
<p>Are you using it as a multimedia thingy? (HP Media Center)</p>
<p>If so, 17" TFT LCD screen, or 15" minimum (17" won't get as much battery power though, but if you really want movies/games, you want 17")</p>
<p>I don't think you're going to need one of the newer intel cpus... the centrino duo platform is some pretty powerful stuff. The older pentium M's will still offer high performance at a lower price.</p>
<p>The exception to this would be if you were running virus software, listening to music, downloading/installing something, and working on Microsoft Word/Excel/etc. all at the same time. Core Duos (Centrino Duo) is much much better at multitasking, especially since the pentium Ms dont have hyperthreading technology.</p>
<p>If you also really want Windows Vista, wait for Merom to come out (codename for Intel's new dual-core 64-bit processor), it should be out somewhere this September.</p>
<p>Another option would be AMD's dualcore Turion64 (or single core), which will be available sooner than Merom. Turion64 is already available, and can run the 64-bit Vista OS. Although the processor itself is more energy efficient than pentium M, the entire platform (chipset, wireless, etc.) is not as efficient as the centrino, so Turion laptops generally have a little less battery life.</p>
<p>If I were you, I'd still stick with Intel for laptop processors though...</p>
<p>As much as Intel sucks when compared to AMD in terms of raw processor technology [in desktops], Intel pwns AMD in mobile technology.</p>
