Thanks I was going to look for one with multi OS support :)

Unless you disk was encrypted, you could have booted up a live distro and back up the files you needed (or even overwrite the shadow file to get a new password)

Also Nvidia is still better for general computing (e.g. openCL). That may change when rustiCL finally catches up, but AMD implementation of openCL always gives problems.

It is solid until you need to use openCL (hopefully this changes when RustiCL beats the closed AMD drivers)

you can always run scripts with the shell they were written for (and you can even argue that people writing scripts should always set the shebang)
