As they say the devil is in the details. Secure boot is an extension of the UEFI. UEFI basically replaces the aging BIOS with updated framework. I boot my home and work computers using a UEFI (Gigabyte) Motherboard and it works great. The Secure Boot farce on the other hand is the "Devil" in the details. If you get hardware with Secure Boot enabled then you can only run "Signed" boot loaders. Windows being the 500 pound gorilla has already pushed their signing keys to the hardware manufacturers. Linux has some projects that are doing the same with a signed grub bootloader. Time will tell, but the take away is look at the hardware you purchase to see if it meets your needs. The big vendors like Dell are only concerned with their bottom lines. They buy the cheapest Chinese motherboards and parts so you don't know what is truely compatible with which OS. If you can build your own or buy from a trusted vendor who puts in higher quality parts. Its worth the extra money to do so.
