Subject says it all... I acquired (on the cheap) a used Surface Pro 3 with the keyboard cover off of a relative who wasn't using it (they said the screen was too small.)
I am considering putting Gentoo (or attempting to) and am wondering if anyone has had success. It looks like newer kernels have some builtin support for the hardware. Due to its form factor I will be setting up distcc to help with the build process, and using -bin packages for monstrosities like firefox and libreoffice. Dan
