Laptop Logic has posted a Black Friday Buyer's Guide for laptop computers.  This year, the hottest deal on the block appears to be the HP Pavilion ze2108wm laptop from Wal-Mart for a smokin' hot $378 with no rebates:

This machine has a lot to offer for the money. Its biggest advantage is the AMD Sempron processor, with PowerNow! technology. While performance will be similar, or even slightly slower than the Celeron M competitors, the big advantage you're going to see here is battery life. This chip has a 25W TDP, higher than the Celeron M's 21W TDP, but the big thing here is PowerNow! The Sempron chip's clock will dynamically fluctuate based on load, just like the Turion 64 and Pentium M. Due to this, users will probably see around 2.5-3 hours of battery life on the reasonable 6 cell battery.
