Laura Breeden bought a new Compaq Presario C304NR notebook in January. She bought it because she wanted to get rid of Windows and all the malware that surrounds it and move to Linux, and her old laptop lacked the memory and power to run Ubuntu Edgy. The salespeople assured her that the C304NR was “Linux ready.” But they didn’t tell her that running Linux would void her warranty.
This is unbelievable. I could understand software related warranties, but to ruin your hardware warranty because of an OS is asinine. Linux is not going to have the ability to simply kill a keyboard. This is something you need to be prepared to deal with though, as it seems to be an "industry standard".
