Difference is your Apple with proprietary battery will cost $3000. I bought my Compaq for under $450 after rebates and promo codes in May of 2007. A replacement battery for mine will cost $130 from Compaq and considerably less from import aftermarket companies that sell on Ebay which I am leery to trust. I am biding my time for the next gen Windows 7 laptops to finally upgrade.
$2499 for the most expensive Macbook Pro; $1199 for the least expensive.

So Compaq's battery costs the same amount as Apple's, despite the fact that the laptop is a lot cheaper. The Mac with a dead battery is a "boat anchor," but the Compaq that needs a new battery at 1/3 its purchase price isn't?
