I haven't timed it but I will time both methods and report back here when I get my hands on the RC. I know that when a Linux live CD is setup on a thumb drive instead of a optical disc it loads much faster and is much more responsive. Installing from a live USB using the built-in installer is about 40% quicker, at least when installing Ubuntu Intrepid or PCLinuxOS 2009. I don't know if you would get comparable results with Win 7. Although it stands to reason that it would considering that USB flash drives are much faster than CD. It seems to me, if my memory serves that installing from my DVD drive took somewhat longer than 16 minutes. Anyway it sounds like it might be fun and informative do do a comparison. I don't have much of anything to do anyways. I'm retired and somewhat a glutton for punishment.
