I have Lion installed on my MacBook Pro now but I want to start fresh. I want it to be as if I just bought this computer new and am turning it on for the first time. Since Lion has no physical disk, how would I go about doing this? I have no DVDs handy, but I was wondering if I could use my iPod classic as a hard drive to hold Lion on? And if so, how would I go about wiping my whole computer and installing Lion fresh? I'm also going to backup my music, documents, and photos to the iPod. Otherwise, this should hopefully be like having a brand new computer, resulting in everything running a bit faster.
