[Thanks to ikilledkenny2]

Highlights:

4 hour 16 mins battery life

Note that the BAPCo MobileMark 2005 performance benchmark seems to have the results mislabeled. I read it as (using the ordering of the battery life test above it):

M1710 Merom: 254
M1710 Yonah: 214
Toshiba: 160

Thus, performance gain of almost 20% going from a 2.16GHz yonah to a 2.33GHz Merom. But if that battery life is true, I say WOW. (But can it really be true???)

Here's another review from Legitreviews:

I dont see how it could have gained a hundred minutes of battery life. That doesn't sound right.

It isn't right... The performance & battery numbers for the C2D were switched - so the real values are 160 minutes battery and 257 performance. The article will be updated shortly...
