I prefer using an old laptop laying around to try Windows 10. For everyone who wants to unleash the full beta awesomeness of this OS and dont have 5,000,000 extra computers (ahh, exaggeration) can to a... dual-boot! Or even better! Take out your current hard drive out of your computer and get a new empty one (preferably Samsung ssd, just because wrestling with Windows setup and "No god dang drivers found" is just a pain the fricking butt.)
