Typo. It's $129, not $119, and $179 for the 17". http://www.apple.com/support/macbookpro/service/battery/
And since most Macbooks and laptops in general are 17” or greater it was a little snarky for you to quote the lower of the 2 prices to compare with the $130 price of the Compaq. $179 freaking dollars for a battery!!!! Just damn... I wonder what the upcharge for a proprietary battery like these new Li-Poly batteries will cost? I am only guessing but they will probably be more than $179...
