Strange...you have a laptop with a GPU which isn't even listed on nVidia's website.
And a few questions:
1) How is the speed of the HDD? The benchmarks look rather low, even compared to my lappy...much slower.
2) What is the dual-mode touchpad like? And isn't the touchpad a bit small?
3) Do they actually send a Win XP CD at all?
Also, have you run 3DMark06, just so that we could try and compare it to the Go 7800/GTX in the Dell Core Duo/Solo forum.
