So by the end of the year, I will buy an ultrabook to replace my heavy laptop which I have to carry almost everyday. I sure hope that Microsoft doesn't lock Linux users out with their secure-boot on x86 devices. Anyway, when I started using Ubuntu, I didn't understand a lot about Linux, but it was strange for me to see so many people complaining on the Internet about issues with drivers, graphic cards, overheating while using Ubuntu. I never had such problems, ever since I installed Ubuntu (started on 11.04), it always adapted just fine on my Toshiba Laptop.
Then I realized that Ubuntu works great out of the box on my laptop because I have Intel dual-core and onboard graphics, which means I have a system that has no proprietary drivers, Intel drivers are not closed. I understood that it is very important to pick carefully the manufacturers in order to have a great experience with Ubuntu and avoid some headaches with incompatibilities (as NVIDIA for example).
So, besides Intel, which other hardware manufacters are more friendly to Linux (Ubuntu in particular)?
