Well, there you go, urluckyday. Now that Astro has given his whole big dissertation on power consumption and what not, I hope you feel that much more informed.
And that laptop actually looks pretty nice for that price. Decent video card, fairly fast (for a laptop CPU) processor, reputable manufacturer. It has Vista on it, which isn't the greatest option for laptops, but it has 2GB of RAM, so it should be able to handle it. I'd say go for it if that's what you're looking for.
have a suggestion for the lf poll? pm me
