It looks like we finally have another widescreen option with the Geforce Go 6600 other than the Toshiba Tecra A4. If you go to the BTO page, there's a link to some benchmarks these guys did. What I especially like about these guys is the fact that they offer Asus notebooks with extended warranties. In addition, this notebook actually supports dual channel DDR2 533 whereas the Toshiba apparently only supports single channel DDR 333 (although the enhanced latency of DDR2 SODIMM's doesn't yield much in terms of performance gains), and the Z71V has a WSXGA screen (1680x1050) whereas the A4 only goes up to 1440x900. Great pricing, too (and they allow you to order it without a HDD, memory, and OS).
