"Here is a short list of the bad chipsets: ATI & Nvidia graphics
chipsets. Go with Intel for graphics."
Things work perfectly on both my desktop PC and laptop, both of which have
nVidia graphics, using the free Nouveau drivers. I have had issues with ATI
though.
"Definitely don't get
a Dell, Lenovo, Toshiba, or HP laptop. I can confirm these companies are
using digital restrictions."
Alienware laptops, made by Dell, don't have restrictions on wireless chipsets
used. I easily replaced the default Broadcom card with an Atheros one in mine
and it didn't complain or anything.
