Hi, so I'm looking into using Linux (Ubuntu), so I already have a laptop but am unsure whether I should boot from USB/CD or get an old laptop just for that purpose.
USB/CD is fine for evaluating a Linux distro in order to decide if you want to keep it but if you plan on using it permanently, I'd advise actually installing it.
