It also seems that Linux hardware support gets worse over time. I upgraded an old laptop to a newer distro, and the CPU fan was constantly blowing, cpu scaling stopped working, video became buggier, Bluetooth would randomly stop working with A2DP, hibernation stopped working. It took nearly a year for me to figure out each of the issues, because this is Linux; we don't "help users" or "test hardware", that would make us soft and weak!
