He asked what's the equivalent. When people ask for the "equivalent", they mean comparable hardware at a similar price. Most techies (who are what Apple's trying to court right now) will want to see similar specs, maybe compare weights, size, etc. We don't really care about immeasurable things like "design" and relatively useless stuff like the "patent pending magnetic power connector" (I have never, ever tripped over my laptops' wires. Neither has my family. And over the course of the last 10 years I've owned 6 laptops).
As for trying to compare, if you honestly don't know what you're talking about, please don't speak. Dual Athlons are not the equivalent of an Intel Core Duo. Dual Athlons are a lot faster and guzzle tremendous amounts of energy. If you want to make a valid comparison, look at the Inspiron 9300 with Core Duo and a similar video card.
Please don't let the reality distortion field and marketingspeak affect what you say to others. This is a big year for Apple to court us geeks, and we really, REALLY don't like the reality distortion field and marketingspeak. Just give us specs and benchmarks. Thanks.
