This one costs a little bit more than $850 but it is the best bang-for-your-buck notebook I've ever seen.

It has things like widescreen display, CD burner and 802.11G wireless (not the slower 802.11b that everybody else has). Basically this notebook would cost double from any other manufacturer. Plus it looks wicked slick.
And I'm not saying this just cuz I own one!
