It will save you pain later as when the preview ends you would have to wipe the drive, install 8 then upgrade to 10. The release update from 8 to 10 will be smooth so retain it just how you have it now.
Hmm, only have about 100 GB left on this hard drive to create a separate partition. I actually want to use the tech preview on my primary computer and partition so that I can interact with it more naturally. That's the best scenario for testing/experiencing it in my opinion. I am aware of the pitfalls of this option, but again I am okay with that.
Are you sure there won't be an upgrade available from the preview to the actual release? I've heard rumors of it going both ways, but nothing definitive. Of course, going from the Consumer Preview of Windows 8 to the actual release did require a clean-install from what I remember, so there is precedent for what you said.
