I have emailed ZTsystems twice, and still no response as to what is in the laptop I'm contemplating. I went to dell.com and 'built' one of their ubuntu laptops, but it ended up costing much more money to get the features I want, and it left out a few things that I think I would love to use. One example is the impossibiliy to change the video hardware at all; If I buy a Linux-ready Dell, then I'm stuck with a Intel Graphics Media Accelerator X3100...

After doing a bit more reasearch, to buy any other laptop, I'd be sacrificing a whole load of power to pay more. Honestly, I'd take my chances right at this second if the support line would respond to my request for a hardware list.
