Do you plan to sell the prebuilt systems with linux preinstalled (or with no OS)? I have no desire for my money to go to Microsoft, and no desire for Windows, but the prebuilt model is intriguing to me.
Preloading a Linux distro is something we may do in the future. We've made the DIY Edition super easy to set up though for folks who don't want Windows in the meantime.
preinstalled linux is a hard requirement for many users, even if they want to reinstall it themselves. It gives an assurance that CPU throttling, suspension, hibernation, will work correctly. Otherwise it feels like a lottery. Of course a linux install is easy and will always work; but will it work correctly? If you offer preinstalled linuxes we can be sure it does.
I'd buy this in a heartbeat if I could get a guarantee that it would work well with Linux. Having Linux pre-installed is one way to signal confidence that it works well with Linux.
