The battry life is almost a deadend discussion since the moment you (as the designer) get 8 hours of battery use, the marketing removes a battery cell or slips in less amp-hours. You'll have to look to reviews to which complete unit has more hours.

As to speed, AMD's 2000+ is about 2.0GHz P4 speed. To compare (non-HT) P4 to Centrino, a rough 2X factor is given to the Centrino's clock speed. This would put the Centrino 1.5 GHz in about the 3.0 GHz Non-HT P4 speed, so it will likely win any CPU benchmark against the 2000+ AMD.

There are 2 excellent buying opportunities for a Toshiba Dothan 1.7 mhz Pentium M (new 2mb L2 system cache) Centrino and a Compaq Athlon 64 3200+ processor notebook

Both have 15.4" widescreen LCD's.

This opportunity, if you are on the west coast, is at Fry's Electronics from 7/9/04-7/13/04 (Friday-Tuesday)

Toshiba M30 series
Pentium M 1.7 Dothan
wi-fi 54g/b
512 mb RAM
80gb hard drive (4200rpm)
dual format DVD burner/CD burner
1999 regular less 150 instant rebate = $1850

Compaq
AMD Athlon 64 3200+
512gb RAM
60gb hard drive (4200 rpm)
DVD burner/CD-RW burner
54g/b wifi
$1530 - 150 instant rebate - 30 mail in rebate = $1350

The Toshiba is thinner and weighs 6.2 pounds (Centrino)
It will get around 3.5-4 hours battery life using wi-fi

The Compaq is a bit heavier as it is based on the Athlon 64. Battery life is lower and the notebook is thicker but it takes advantage of upcoming 64bit technology in Windows XP Service Pack 2 and Longhorn in 2006.
