The Precision 7510 weights 6 pounds, which is about a half pound lighter than what the 17 inch macbook pro used to weigh. (750 grams heavier than the current 15 inch macbook pro). So... it falls squarely into Macbook Pro range. Now.. if you're looking for a Macbook Air, of course, this won't come anywhere close to to that. This is not to say that you'd accept this as a Macbook Pro, but your statement about it not being an alternative to the Macbook Pro is clearly not true. Personally, I often carry around a 40 pound weight (4-year-old daughter), so for me the difference is negligible.
